      "message": "reintroduce accept4\n\nIntroduce a new accept4() system call.  The addition of this system call\nmatches analogous changes in 2.6.27 (dup3(), evenfd2(), signalfd4(),\ninotify_init1(), epoll_create1(), pipe2()) which added new system calls\nthat differed from analogous traditional system calls in adding a flags\nargument that can be used to access additional functionality.\n\nThe accept4() system call is exactly the same as accept(), except that\nit adds a flags bit-mask argument.  Two flags are initially implemented.\n(Most of the new system calls in 2.6.27 also had both of these flags.)\n\nSOCK_CLOEXEC causes the close-on-exec (FD_CLOEXEC) flag to be enabled\nfor the new file descriptor returned by accept4().  This is a useful\nsecurity feature to avoid leaking information in a multithreaded\nprogram where one thread is doing an accept() at the same time as\nanother thread is doing a fork() plus exec().  More details here:\nhttp://udrepper.livejournal.com/20407.html \"Secure File Descriptor Handling\",\nUlrich Drepper).\n\nThe other flag is SOCK_NONBLOCK, which causes the O_NONBLOCK flag\nto be enabled on the new open file description created by accept4().\n(This flag is merely a convenience, saving the use of additional calls\nfcntl(F_GETFL) and fcntl (F_SETFL) to achieve the same result.\n\nHere\u0027s a test program.  Works on x86-32.

      "message": "flag parameters: paccept\n\nThis patch is by far the most complex in the series.  It adds a new syscall\npaccept.  This syscall differs from accept in that it adds (at the userlevel)\ntwo additional parameters:\n\n- a signal mask\n- a flags value\n\nThe flags parameter can be used to set flag like SOCK_CLOEXEC.  This is\nimlpemented here as well.  Some people argued that this is a property which\nshould be inherited from the file desriptor for the server but this is against\nPOSIX.  Additionally, we really want the signal mask parameter as well\n(similar to pselect, ppoll, etc).  So an interface change in inevitable.\n\nThe flag value is the same as for socket and socketpair.  I think diverging\nhere will only create confusion.  Similar to the filesystem interfaces where\nthe use of the O_* constants differs, it is acceptable here.\n\nThe signal mask is handled as for pselect etc.  The mask is temporarily\ninstalled for the thread and removed before the call returns.  I modeled the\ncode after pselect.  If there is a problem it\u0027s likely also in pselect.\n\nFor architectures which use socketcall I maintained this interface instead of\nadding a system call.  The symmetry shouldn\u0027t be broken.\n\nThe following test must be adjusted for architectures other than x86 and\nx86-64 and in case the syscall numbers changed.\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n#include \u003cerrno.h\u003e\n#include \u003cfcntl.h\u003e\n#include \u003cpthread.h\u003e\n#include \u003csignal.h\u003e\n#include \u003cstdio.h\u003e\n#include \u003cunistd.h\u003e\n#include \u003cnetinet/in.h\u003e\n#include \u003csys/socket.h\u003e\n#include \u003csys/syscall.h\u003e\n\n#ifndef __NR_paccept\n# ifdef __x86_64__\n#  define __NR_paccept 288\n# elif defined __i386__\n#  define SYS_PACCEPT 18\n#  define USE_SOCKETCALL 1\n# else\n#  error \"need __NR_paccept\"\n# endif\n#endif\n\n#ifdef USE_SOCKETCALL\n# define paccept(fd, addr, addrlen, mask, flags) \\\n  ({ long args[6] \u003d { \\\n       (long) fd, (long) addr, (long) addrlen, (long) mask, 8, (long) flags }; \\\n     syscall (__NR_socketcall, SYS_PACCEPT, args); })\n#else\n# define paccept(fd, addr, addrlen, mask, flags) \\\n  syscall (__NR_paccept, fd, addr, addrlen, mask, 8, flags)\n#endif\n\n#define PORT 57392\n\n#define SOCK_CLOEXEC O_CLOEXEC\n\nstatic pthread_barrier_t b;\n\nstatic void *\ntf (void *arg)\n{\n  pthread_barrier_wait (\u0026b);\n  int s \u003d socket (AF_INET, SOCK_STREAM, 0);\n  struct sockaddr_in sin;\n  sin.sin_family \u003d AF_INET;\n  sin.sin_addr.s_addr \u003d htonl (INADDR_LOOPBACK);\n  sin.sin_port \u003d htons (PORT);\n  connect (s, (const struct sockaddr *) \u0026sin, sizeof (sin));\n  close (s);\n\n  pthread_barrier_wait (\u0026b);\n  s \u003d socket (AF_INET, SOCK_STREAM, 0);\n  sin.sin_port \u003d htons (PORT);\n  connect (s, (const struct sockaddr *) \u0026sin, sizeof (sin));\n  close (s);\n  pthread_barrier_wait (\u0026b);\n\n  pthread_barrier_wait (\u0026b);\n  sleep (2);\n  pthread_kill ((pthread_t) arg, SIGUSR1);\n\n  return NULL;\n}\n\nstatic void\nhandler (int s)\n{\n}\n\nint\nmain (void)\n{\n  pthread_barrier_init (\u0026b, NULL, 2);\n\n  struct sockaddr_in sin;\n  pthread_t th;\n  if (pthread_create (\u0026th, NULL, tf, (void *) pthread_self ()) !\u003d 0)\n    {\n      puts (\"pthread_create failed\");\n      return 1;\n    }\n\n  int s \u003d socket (AF_INET, SOCK_STREAM, 0);\n  int reuse \u003d 1;\n  setsockopt (s, SOL_SOCKET, SO_REUSEADDR, \u0026reuse, sizeof (reuse));\n  sin.sin_family \u003d AF_INET;\n  sin.sin_addr.s_addr \u003d htonl (INADDR_LOOPBACK);\n  sin.sin_port \u003d htons (PORT);\n  bind (s, (struct sockaddr *) \u0026sin, sizeof (sin));\n  listen (s, SOMAXCONN);\n\n  pthread_barrier_wait (\u0026b);\n\n  int s2 \u003d paccept (s, NULL, 0, NULL, 0);\n  if (s2 \u003c 0)\n    {\n      puts (\"paccept(0) failed\");\n      return 1;\n    }\n\n  int coe \u003d fcntl (s2, F_GETFD);\n  if (coe \u0026 FD_CLOEXEC)\n    {\n      puts (\"paccept(0) set close-on-exec-flag\");\n      return 1;\n    }\n  close (s2);\n\n  pthread_barrier_wait (\u0026b);\n\n  s2 \u003d paccept (s, NULL, 0, NULL, SOCK_CLOEXEC);\n  if (s2 \u003c 0)\n    {\n      puts (\"paccept(SOCK_CLOEXEC) failed\");\n      return 1;\n    }\n\n  coe \u003d fcntl (s2, F_GETFD);\n  if ((coe \u0026 FD_CLOEXEC) \u003d\u003d 0)\n    {\n      puts (\"paccept(SOCK_CLOEXEC) does not set close-on-exec flag\");\n      return 1;\n    }\n  close (s2);\n\n  pthread_barrier_wait (\u0026b);\n\n  struct sigaction sa;\n  sa.sa_handler \u003d handler;\n  sa.sa_flags \u003d 0;\n  sigemptyset (\u0026sa.sa_mask);\n  sigaction (SIGUSR1, \u0026sa, NULL);\n\n  sigset_t ss;\n  pthread_sigmask (SIG_SETMASK, NULL, \u0026ss);\n  sigaddset (\u0026ss, SIGUSR1);\n  pthread_sigmask (SIG_SETMASK, \u0026ss, NULL);\n\n  sigdelset (\u0026ss, SIGUSR1);\n  alarm (4);\n  pthread_barrier_wait (\u0026b);\n\n  errno \u003d 0 ;\n  s2 \u003d paccept (s, NULL, 0, \u0026ss, 0);\n  if (s2 !\u003d -1 || errno !\u003d EINTR)\n    {\n      puts (\"paccept did not fail with EINTR\");\n      return 1;\n    }\n\n  close (s);\n\n  puts (\"OK\");\n\n  return 0;\n}\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\n[akpm@linux-foundation.org: make it compile]\n[akpm@linux-foundation.org: add sys_ni stub]\nSigned-off-by: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nAcked-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nCc: Michael Kerrisk \u003cmtk.manpages@googlemail.com\u003e\nCc: \u003clinux-arch@vger.kernel.org\u003e\nCc: \"David S.

It can be used instead of pipe(2) in all cases where those\nwould simply be used to signal events.  Their kernel overhead is much lower\nthan pipes, and they do not consume two fds.  When used in the kernel, it can\noffer an fd-bridge to enable, for example, functionalities like KAIO or\nsyslets/threadlets to signal to an fd the completion of certain operations.\nBut more in general, an eventfd can be used by the kernel to signal readiness,\nin a POSIX poll/select way, of interfaces that would otherwise be incompatible\nwith it.  The API is:\n\nint eventfd(unsigned int count);\n\nThe eventfd API accepts an initial \"count\" parameter, and returns an eventfd\nfd.  It supports poll(2) (POLLIN, POLLOUT, POLLERR), read(2) and write(2).\n\nThe POLLIN flag is raised when the internal counter is greater than zero.\n\nThe POLLOUT flag is raised when at least a value of \"1\" can be written to the\ninternal counter.\n\nThe POLLERR flag is raised when an overflow in the counter value is detected.\n\nThe write(2) operation can never overflow the counter, since it blocks (unless\nO_NONBLOCK is set, in which case -EAGAIN is returned).\n\nBut the eventfd_signal() function can do it, since it\u0027s supposed to not sleep\nduring its operation.\n\nThe read(2) function reads the __u64 counter value, and reset the internal\nvalue to zero.  If the value read is equal to (__u64) -1, an overflow happened\non the internal counter (due to 2^64 eventfd_signal() posts that has never\nbeen retired - unlickely, but possible).\n\nThe write(2) call writes an __u64 count value, and adds it to the current\ncounter.  The eventfd fd supports O_NONBLOCK also.\n\nOn the kernel side, we have:\n\nstruct file *eventfd_fget(int fd);\nint eventfd_signal(struct file *file, unsigned int n);\n\nThe eventfd_fget() should be called to get a struct file* from an eventfd fd\n(this is an fget() + check of f_op being an eventfd fops pointer).\n\nThe kernel can then call eventfd_signal() every time it wants to post an event\nto userspace.  The eventfd_signal() function can be called from any context.\nAn eventfd() simple test and bench is available here:\n\nhttp://www.xmailserver.org/eventfd-bench.c\n\nThis is the eventfd-based version of pipetest-4 (pipe(2) based):\n\nhttp://www.xmailserver.org/pipetest-4.c\n\nNot that performance matters much in the eventfd case, but eventfd-bench\nshows almost as double as performance than pipetest-4.\n\n[akpm@linux-foundation.org: fix i386 build]\n[akpm@linux-foundation.org: add sys_eventfd to sys_ni.c]\nSigned-off-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "signal/timer/event: signalfd core\n\nThis patch series implements the new signalfd() system call.\n\nI took part of the original Linus code (and you know how badly it can be\nbroken :), and I added even more breakage ;) Signals are fetched from the same\nsignal queue used by the process, so signalfd will compete with standard\nkernel delivery in dequeue_signal().  If you want to reliably fetch signals on\nthe signalfd file, you need to block them with sigprocmask(SIG_BLOCK).  This\nseems to be working fine on my Dual Opteron machine.  I made a quick test\nprogram for it:\n\nhttp://www.xmailserver.org/signafd-test.c\n\nThe signalfd() system call implements signal delivery into a file descriptor\nreceiver.  The signalfd file descriptor if created with the following API:\n\nint signalfd(int ufd, const sigset_t *mask, size_t masksize);\n\nThe \"ufd\" parameter allows to change an existing signalfd sigmask, w/out going\nto close/create cycle (Linus idea).  Use \"ufd\" \u003d\u003d -1 if you want a brand new\nsignalfd file.\n\nThe \"mask\" allows to specify the signal mask of signals that we are interested\nin.  The \"masksize\" parameter is the size of \"mask\".\n\nThe signalfd fd supports the poll(2) and read(2) system calls.  The poll(2)\nwill return POLLIN when signals are available to be dequeued.  As a direct\nconsequence of supporting the Linux poll subsystem, the signalfd fd can use\nused together with epoll(2) too.\n\nThe read(2) system call will return a \"struct signalfd_siginfo\" structure in\nthe userspace supplied buffer.  The return value is the number of bytes copied\nin the supplied buffer, or -1 in case of error.  The read(2) call can also\nreturn 0, in case the sighand structure to which the signalfd was attached,\nhas been orphaned.  The O_NONBLOCK flag is also supported, and read(2) will\nreturn -EAGAIN in case no signal is available.\n\nIf the size of the buffer passed to read(2) is lower than sizeof(struct\nsignalfd_siginfo), -EINVAL is returned.  A read from the signalfd can also\nreturn -ERESTARTSYS in case a signal hits the process.  The format of the\nstruct signalfd_siginfo is, and the valid fields depends of the (-\u003ecode \u0026\n__SI_MASK) value, in the same way a struct siginfo would:\n\nstruct signalfd_siginfo {\n\t__u32 signo;\t/* si_signo */\n\t__s32 err;\t/* si_errno */\n\t__s32 code;\t/* si_code */\n\t__u32 pid;\t/* si_pid */\n\t__u32 uid;\t/* si_uid */\n\t__s32 fd;\t/* si_fd */\n\t__u32 tid;\t/* si_fd */\n\t__u32 band;\t/* si_band */\n\t__u32 overrun;\t/* si_overrun */\n\t__u32 trapno;\t/* si_trapno */\n\t__s32 status;\t/* si_status */\n\t__s32 svint;\t/* si_int */\n\t__u64 svptr;\t/* si_ptr */\n\t__u64 utime;\t/* si_utime */\n\t__u64 stime;\t/* si_stime */\n\t__u64 addr;\t/* si_addr */\n};\n\n[akpm@linux-foundation.org: fix signalfd_copyinfo() on i386]\nSigned-off-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "[PATCH] pi-futex: futex code cleanups\n\nWe are pleased to announce \"lightweight userspace priority inheritance\" (PI)\nsupport for futexes.  The following patchset and glibc patch implements it,\nontop of the robust-futexes patchset which is included in 2.6.16-mm1.\n\nWe are calling it lightweight for 3 reasons:\n\n - in the user-space fastpath a PI-enabled futex involves no kernel work\n   (or any other PI complexity) at all.  No registration, no extra kernel\n   calls - just pure fast atomic ops in userspace.\n\n - in the slowpath (in the lock-contention case), the system call and\n   scheduling pattern is in fact better than that of normal futexes, due to\n   the \u0027integrated\u0027 nature of FUTEX_LOCK_PI.  [more about that further down]\n\n - the in-kernel PI implementation is streamlined around the mutex\n   abstraction, with strict rules that keep the implementation relatively\n   simple: only a single owner may own a lock (i.e.  no read-write lock\n   support), only the owner may unlock a lock, no recursive locking, etc.\n\n  Priority Inheritance - why, oh why???\n  -------------------------------------\n\nMany of you heard the horror stories about the evil PI code circling Linux for\nyears, which makes no real sense at all and is only used by buggy applications\nand which has horrible overhead.  Some of you have dreaded this very moment,\nwhen someone actually submits working PI code ;-)\n\nSo why would we like to see PI support for futexes?\n\nWe\u0027d like to see it done purely for technological reasons.  We dont think it\u0027s\na buggy concept, we think it\u0027s useful functionality to offer to applications,\nwhich functionality cannot be achieved in other ways.  We also think it\u0027s the\nright thing to do, and we think we\u0027ve got the right arguments and the right\nnumbers to prove that.  We also believe that we can address all the\ncounter-arguments as well.  For these reasons (and the reasons outlined below)\nwe are submitting this patch-set for upstream kernel inclusion.\n\nWhat are the benefits of PI?\n\n  The short reply:\n  ----------------\n\nUser-space PI helps achieving/improving determinism for user-space\napplications.  In the best-case, it can help achieve determinism and\nwell-bound latencies.  Even in the worst-case, PI will improve the statistical\ndistribution of locking related application delays.\n\n  The longer reply:\n  -----------------\n\nFirstly, sharing locks between multiple tasks is a common programming\ntechnique that often cannot be replaced with lockless algorithms.  As we can\nsee it in the kernel [which is a quite complex program in itself], lockless\nstructures are rather the exception than the norm - the current ratio of\nlockless vs.  locky code for shared data structures is somewhere between 1:10\nand 1:100.  Lockless is hard, and the complexity of lockless algorithms often\nendangers to ability to do robust reviews of said code.  I.e.  critical RT\napps often choose lock structures to protect critical data structures, instead\nof lockless algorithms.  Furthermore, there are cases (like shared hardware,\nor other resource limits) where lockless access is mathematically impossible.\n\nMedia players (such as Jack) are an example of reasonable application design\nwith multiple tasks (with multiple priority levels) sharing short-held locks:\nfor example, a highprio audio playback thread is combined with medium-prio\nconstruct-audio-data threads and low-prio display-colory-stuff threads.  Add\nvideo and decoding to the mix and we\u0027ve got even more priority levels.\n\nSo once we accept that synchronization objects (locks) are an unavoidable fact\nof life, and once we accept that multi-task userspace apps have a very fair\nexpectation of being able to use locks, we\u0027ve got to think about how to offer\nthe option of a deterministic locking implementation to user-space.\n\nMost of the technical counter-arguments against doing priority inheritance\nonly apply to kernel-space locks.  But user-space locks are different, there\nwe cannot disable interrupts or make the task non-preemptible in a critical\nsection, so the \u0027use spinlocks\u0027 argument does not apply (user-space spinlocks\nhave the same priority inversion problems as other user-space locking\nconstructs).  Fact is, pretty much the only technique that currently enables\ngood determinism for userspace locks (such as futex-based pthread mutexes) is\npriority inheritance:\n\nCurrently (without PI), if a high-prio and a low-prio task shares a lock [this\nis a quite common scenario for most non-trivial RT applications], even if all\ncritical sections are coded carefully to be deterministic (i.e.  all critical\nsections are short in duration and only execute a limited number of\ninstructions), the kernel cannot guarantee any deterministic execution of the\nhigh-prio task: any medium-priority task could preempt the low-prio task while\nit holds the shared lock and executes the critical section, and could delay it\nindefinitely.\n\n  Implementation:\n  ---------------\n\nAs mentioned before, the userspace fastpath of PI-enabled pthread mutexes\ninvolves no kernel work at all - they behave quite similarly to normal\nfutex-based locks: a 0 value means unlocked, and a value\u003d\u003dTID means locked.\n(This is the same method as used by list-based robust futexes.) Userspace uses\natomic ops to lock/unlock these mutexes without entering the kernel.\n\nTo handle the slowpath, we have added two new futex ops:\n\n  FUTEX_LOCK_PI\n  FUTEX_UNLOCK_PI\n\nIf the lock-acquire fastpath fails, [i.e.  an atomic transition from 0 to TID\nfails], then FUTEX_LOCK_PI is called.  The kernel does all the remaining work:\nif there is no futex-queue attached to the futex address yet then the code\nlooks up the task that owns the futex [it has put its own TID into the futex\nvalue], and attaches a \u0027PI state\u0027 structure to the futex-queue.  The pi_state\nincludes an rt-mutex, which is a PI-aware, kernel-based synchronization\nobject.  The \u0027other\u0027 task is made the owner of the rt-mutex, and the\nFUTEX_WAITERS bit is atomically set in the futex value.  Then this task tries\nto lock the rt-mutex, on which it blocks.  Once it returns, it has the mutex\nacquired, and it sets the futex value to its own TID and returns.  Userspace\nhas no other work to perform - it now owns the lock, and futex value contains\nFUTEX_WAITERS|TID.\n\nIf the unlock side fastpath succeeds, [i.e.  userspace manages to do a TID -\u003e\n0 atomic transition of the futex value], then no kernel work is triggered.\n\nIf the unlock fastpath fails (because the FUTEX_WAITERS bit is set), then\nFUTEX_UNLOCK_PI is called, and the kernel unlocks the futex on the behalf of\nuserspace - and it also unlocks the attached pi_state-\u003ert_mutex and thus wakes\nup any potential waiters.\n\nNote that under this approach, contrary to other PI-futex approaches, there is\nno prior \u0027registration\u0027 of a PI-futex.  [which is not quite possible anyway,\ndue to existing ABI properties of pthread mutexes.]\n\nAlso, under this scheme, \u0027robustness\u0027 and \u0027PI\u0027 are two orthogonal properties\nof futexes, and all four combinations are possible: futex, robust-futex,\nPI-futex, robust+PI-futex.\n\n  glibc support:\n  --------------\n\nUlrich Drepper and Jakub Jelinek have written glibc support for PI-futexes\n(and robust futexes), enabling robust and PI (PTHREAD_PRIO_INHERIT) POSIX\nmutexes.  (PTHREAD_PRIO_PROTECT support will be added later on too, no\nadditional kernel changes are needed for that).  [NOTE: The glibc patch is\nobviously inofficial and unsupported without matching upstream kernel\nfunctionality.]\n\nthe patch-queue and the glibc patch can also be downloaded from:\n\n  http://redhat.com/~mingo/PI-futex-patches/\n\nMany thanks go to the people who helped us create this kernel feature: Steven\nRostedt, Esben Nielsen, Benedikt Spranger, Daniel Walker, John Cooper, Arjan\nvan de Ven, Oleg Nesterov and others.  Credits for related prior projects goes\nto Dirk Grambow, Inaky Perez-Gonzalez, Bill Huey and many others.\n\nClean up the futex code, before adding more features to it:\n\n - use u32 as the futex field type - that\u0027s the ABI\n - use __user and pointers to u32 instead of unsigned long\n - code style / comment style cleanups\n - rename hash-bucket name from \u0027bh\u0027 to \u0027hb\u0027.\n\nI checked the pre and post futex.o object files to make sure this\npatch has no code effects.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nCc: Jakub Jelinek \u003cjakub@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

The function can\nbe used to determine the location of pages and to move them onto the desired\nnode. move_pages() returns status information for each page.\n\nlong move_pages(pid, number_of_pages_to_move,\n\t\taddresses_of_pages[],\n\t\tnodes[] or NULL,\n\t\tstatus[],\n\t\tflags);\n\nThe addresses of pages is an array of void * pointing to the\npages to be moved.\n\nThe nodes array contains the node numbers that the pages should be moved\nto. If a NULL is passed instead of an array then no pages are moved but\nthe status array is updated. The status request may be used to determine\nthe page state before issuing another move_pages() to move pages.\n\nThe status array will contain the state of all individual page migration\nattempts when the function terminates. The status array is only valid if\nmove_pages() completed successfullly.\n\nPossible page states in status[]:\n\n0..MAX_NUMNODES\tThe page is now on the indicated node.\n\n-ENOENT\t\tPage is not present\n\n-EACCES\t\tPage is mapped by multiple processes and can only\n\t\tbe moved if MPOL_MF_MOVE_ALL is specified.\n\n-EPERM\t\tThe page has been mlocked by a process/driver and\n\t\tcannot be moved.\n\n-EBUSY\t\tPage is busy and cannot be moved.

Things which would require two or three syscalls with\n  fadvise() can be done in a single syscall.\n\n- Using fadvise() in this manner is something not covered by POSIX.\n\nThe patch wires up the syscall for x86.\n\nThe sycall is implemented in the new fs/sync.c.  The intention is that we can\nmove sys_fsync(), sys_fdatasync() and perhaps sys_sync() into there later.\n\nDocumentation for the syscall is in fs/sync.c.\n\nA test app (sync_file_range.c) is in\nhttp://www.zip.com.au/~akpm/linux/patches/stuff/ext3-tools.tar.gz.\n\nThe available-to-GPL-modules do_sync_file_range() is for knfsd: \"A COMMIT can\nsay NFS_DATA_SYNC or NFS_FILE_SYNC.

A process may\nhave migrated to another node.  Memory was allocated optimally for the prior\ncontext.  sys_migrate_pages allows to shift the memory to the new node.\n\nsys_migrate_pages is also useful if the processes available memory nodes have\nchanged through cpuset operations to manually move the processes memory.  Paul\nJackson is working on an automated mechanism that will allow an automatic\nmigration if the cpuset of a process is changed.  However, a user may decide\nto manually control the migration.\n\nThis implementation is put into the policy layer since it uses concepts and\nfunctions that are also needed for mbind and friends.  The patch also provides\na do_migrate_pages function that may be useful for cpusets to automatically\nmove memory.  sys_migrate_pages does not modify policies in contrast to Ray\u0027s\nimplementation.\n\nThe current code here is based on the swap based page migration capability and\nthus is not able to preserve the physical layout relative to it containing\nnodeset (which may be a cpuset).  When direct page migration becomes available\nthen the implementation needs to be changed to do a isomorphic move of pages\nbetween different nodesets.  The current implementation simply evicts all\npages in source nodeset that are not in the target nodeset.\n\nPatch supports ia64, i386 and x86_64.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
