      "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.

Without this patch, the user-agent is\nforced to choose a memory block to remove randomly.\n\nSample output of the sysfs files:\n\n./memory/memory0/removable: 0\n./memory/memory1/removable: 0\n./memory/memory2/removable: 0\n./memory/memory3/removable: 0\n./memory/memory4/removable: 0\n./memory/memory5/removable: 0\n./memory/memory6/removable: 0\n./memory/memory7/removable: 1\n./memory/memory8/removable: 0\n./memory/memory9/removable: 0\n./memory/memory10/removable: 0\n./memory/memory11/removable: 0\n./memory/memory12/removable: 0\n./memory/memory13/removable: 0\n./memory/memory14/removable: 0\n./memory/memory15/removable: 0\n./memory/memory16/removable: 0\n./memory/memory17/removable: 1\n./memory/memory18/removable: 1\n./memory/memory19/removable: 1\n./memory/memory20/removable: 1\n./memory/memory21/removable: 1\n./memory/memory22/removable: 1\n\nSigned-off-by: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "mm: record MAP_NORESERVE status on vmas and fix small page mprotect reservations\n\nWith Mel\u0027s hugetlb private reservation support patches applied, strict\novercommit semantics are applied to both shared and private huge page\nmappings.  This can be a problem if an application relied on unlimited\novercommit semantics for private mappings.  An example of this would be an\napplication which maps a huge area with the intention of using it very\nsparsely.  These application would benefit from being able to opt-out of\nthe strict overcommit.  It should be noted that prior to hugetlb\nsupporting demand faulting all mappings were fully populated and so\napplications of this type should be rare.\n\nThis patch stack implements the MAP_NORESERVE mmap() flag for huge page\nmappings.  This flag has the same meaning as for small page mappings,\nsuppressing reservations for that mapping.\n\nThanks to Mel Gorman for reviewing a number of early versions of these\npatches.\n\nThis patch:\n\nWhen a small page mapping is created with mmap() reservations are created\nby default for any memory pages required.  When the region is read/write\nthe reservation is increased for every page, no reservation is needed for\nread-only regions (as they implicitly share the zero page).  Reservations\nare tracked via the VM_ACCOUNT vma flag which is present when the region\nhas reservation backing it.  When we convert a region from read-only to\nread-write new reservations are aquired and VM_ACCOUNT is set.  However,\nwhen a read-only map is created with MAP_NORESERVE it is indistinguishable\nfrom a normal mapping.  When we then convert that to read/write we are\nforced to incorrectly create reservations for it as we have no record of\nthe original MAP_NORESERVE.\n\nThis patch introduces a new vma flag VM_NORESERVE which records the\npresence of the original MAP_NORESERVE flag.  This allows us to\ndistinguish these two circumstances and correctly account the reserve.\n\nAs well as fixing this FIXME in the code, this makes it much easier to\nintroduce MAP_NORESERVE support for huge pages as this flag is available\nconsistantly for the life of the mapping.  VM_ACCOUNT on the other hand is\nheavily used at the generic level in association with small pages.\n\nSigned-off-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Johannes Weiner \u003channes@saeurebad.de\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Michael Kerrisk \u003cmtk.manpages@googlemail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "hugetlb: guarantee that COW faults for a process that called mmap(MAP_PRIVATE) on hugetlbfs will succeed\n\nAfter patch 2 in this series, a process that successfully calls mmap() for\na MAP_PRIVATE mapping will be guaranteed to successfully fault until a\nprocess calls fork().  At that point, the next write fault from the parent\ncould fail due to COW if the child still has a reference.\n\nWe only reserve pages for the parent but a copy must be made to avoid\nleaking data from the parent to the child after fork().  Reserves could be\ntaken for both parent and child at fork time to guarantee faults but if\nthe mapping is large it is highly likely we will not have sufficient pages\nfor the reservation, and it is common to fork only to exec() immediatly\nafter.  A failure here would be very undesirable.\n\nNote that the current behaviour of mainline with MAP_PRIVATE pages is\npretty bad.  The following situation is allowed to occur today.\n\n1. Process calls mmap(MAP_PRIVATE)\n2. Process calls mlock() to fault all pages and makes sure it succeeds\n3. Process forks()\n4. Process writes to MAP_PRIVATE mapping while child still exists\n5. If the COW fails at this point, the process gets SIGKILLed even though it\n   had taken care to ensure the pages existed\n\nThis patch improves the situation by guaranteeing the reliability of the\nprocess that successfully calls mmap().  When the parent performs COW, it\nwill try to satisfy the allocation without using reserves.  If that fails\nthe parent will steal the page leaving any children without a page.\nFaults from the child after that point will result in failure.  If the\nchild COW happens first, an attempt will be made to allocate the page\nwithout reserves and the child will get SIGKILLed on failure.\n\nTo summarise the new behaviour:\n\n1. If the original mapper performs COW on a private mapping with multiple\n   references, it will attempt to allocate a hugepage from the pool or\n   the buddy allocator without using the existing reserves. On fail, VMAs\n   mapping the same area are traversed and the page being COW\u0027d is unmapped\n   where found. It will then steal the original page as the last mapper in\n   the normal way.\n\n2. The VMAs the pages were unmapped from are flagged to note that pages\n   with data no longer exist. Future no-page faults on those VMAs will\n   terminate the process as otherwise it would appear that data was corrupted.\n   A warning is printed to the console that this situation occured.\n\n2. If the child performs COW first, it will attempt to satisfy the COW\n   from the pool if there are enough pages or via the buddy allocator if\n   overcommit is allowed and the buddy allocator can satisfy the request. If\n   it fails, the child will be killed.\n\nIf the pool is large enough, existing applications will not notice that\nthe reserves were a factor.  Existing applications depending on the\nno-reserves been set are unlikely to exist as for much of the history of\nhugetlbfs, pages were prefaulted at mmap(), allocating the pages at that\npoint or failing the mmap().\n\n[npiggin@suse.de: fix CONFIG_HUGETLB\u003dn build]\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

This guarantees that a process that successfully calls\nmmap() will successfully fault all pages in the future unless fork() is\ncalled.\n\nThe characteristics of private mappings of hugetlbfs files behaviour after\nthis patch are;\n\n1. The process calling mmap() is guaranteed to succeed all future faults until\n   it forks().\n2. On fork(), the parent may die due to SIGKILL on writes to the private\n   mapping if enough pages are not available for the COW. For reasonably\n   reliable behaviour in the face of a small huge page pool, children of\n   hugepage-aware processes should not reference the mappings; such as\n   might occur when fork()ing to exec().\n3. On fork(), the child VMAs inherit no reserves. Reads on pages already\n   faulted by the parent will succeed. Successful writes will depend on enough\n   huge pages being free in the pool.\n4. Quotas of the hugetlbfs mount are checked at reserve time for the mapper\n   and at fault time otherwise.\n\nBefore this patch, all reads or writes in the child potentially needs page\nallocations that can later lead to the death of the parent.  This applies\nto reads and writes of uninstantiated pages as well as COW.  After the\npatch it is only a write to an instantiated page that causes problems.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "page-flags: record page flag overlays explicitly\n\nWith the recent page flag reorganisation we have a single enum which\ndefines the valid page flags and their values, nice and clear.  However\nthere are a number of bits which are overloaded by different subsystems.\nFirstly there is PG_owner_priv_1 which is used by filesystems and by XEN.\nSecondly both SLOB and SLUB use a couple of extra page bits to manage\ninternal state for pages they own; both overlay other bits.  All of these\n\"aliases\" are scattered about the source making it very hard for a reader\nto know if the bits are safe to rely on in all contexts; confusion here is\nbad.\n\nAs we now have a single place where the bits are clearly assigned it makes\nsense to clarify the reuse of bits by making the aliases explicit and\nvisible with the original bit assignments.  This patch creates explicit\naliases within the enum itself for the overloaded bits, creates standard\nbit accessors PageFoo etc.  and uses those throughout.\n\nThis version pulls the bit manipulation out to standard named page bit\naccessors as suggested by Christoph, it retains the explicit mapping to\nthe overlayed bits.  A fusion of both ideas.  This has been SLUB and SLOB\nhave been compile tested on x86_64 only, and SLUB boot tested.  If people\nfeel this is worth doing then I can run a fuller set of testing.\n\nThis patch:\n\nSome page flags are used for more than one purpose, for example\nPG_owner_priv_1.  Currently there are individual accessors for each user,\neach built using the common flag name far away from the bit definitions.\nThis makes it hard to see all possible uses of these bits.\n\nNow that we have a single enum to generate the bit orders it makes sense\nto express overlays in the same place.  So create per use aliases for this\nbit in the main page-flags enum and use those in the accessors.\n\n[akpm@linux-foundation.org: fix xen]\nSigned-off-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Matt Mackall \u003cmpm@selenic.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

This list can be very long if there is huge free memory.\n\n- the problem\n\n  When shrink_dcache_sb() is called, it scans all dentry_unused linearly\n  under spin_lock(), and if dentry-\u003ed_sb is differnt from given\n  superblock, scan next dentry.  This scan costs very much if there are\n  many entries, and very ineffective if there are many superblocks.\n\n  IOW, When we need to shrink unused dentries on one dentry, but scans\n  unused dentries on all superblocks in the system.  For example, we scan\n  500 dentries to unmount a filesystem, but scans 1,000,000 or more unused\n  dentries on other superblocks.\n\n  In our case , At mounting NFS*, shrink_dcache_sb() is called to shrink\n  unused dentries on NFS, but scans 100,000,000 unused dentries on\n  superblocks in the system such as local ext3 filesystems.  I hear NFS\n  mounting took 1 min on some system in use.\n\n* : NFS uses virtual filesystem in rpc layer, so NFS is affected by\n  this problem.\n\n  100,000,000 is possible number on large systems.\n\n  Per-superblock LRU of unused dentried can reduce the cost in\n  reasonable manner.\n\n- How to fix\n\n  I found this problem is solved by David Chinner\u0027s \"Per-superblock\n  unused dentry LRU lists V3\"(1), so I rebase it and add some fix to\n  reclaim with fairness, which is in Andrew Morton\u0027s comments(2).\n\n  1) http://lkml.org/lkml/2006/5/25/318\n  2) http://lkml.org/lkml/2006/5/25/320\n\n  Split LRU-list of unused dentries to each superblocks.  Then, NFS\n  mounting will check dentries under a superblock instead of all.  But\n  this spliting will break LRU of dentry-unused.  So, I\u0027ve attempted to\n  make reclaim unused dentrins with fairness by calculate number of\n  dentries to scan on this sb based on following way\n\n  number of dentries to scan on this sb \u003d\n  count * (number of dentries on this sb / number of dentries in the machine)\n\n- ToDo\n - I have to measuring performance number and do stress tests.\n\n - When unmount occurs during prune_dcache(), scanning on same\n  superblock, It is unable to reach next superblock because it is gone\n  away.  We restart scannig superblock from first one, it causes\n  unfairness of reclaim unused dentries on first superblock.  But I think\n  this happens very rarely.\n\n- Test Results\n\n  Result on 6GB boxes with excessive unused dentries.\n\nWithout patch:\n\n$ cat /proc/sys/fs/dentry-state\n10181835        10180203        45      0       0       0\n# mount -t nfs 10.124.60.70:/work/kernel-src nfs\nreal    0m1.830s\nuser    0m0.001s\nsys     0m1.653s\n\n With this patch:\n$ cat /proc/sys/fs/dentry-state\n10236610        10234751        45      0       0       0\n# mount -t nfs 10.124.60.70:/work/kernel-src nfs\nreal    0m0.106s\nuser    0m0.002s\nsys     0m0.032s\n\n[akpm@linux-foundation.org: fix comments]\nSigned-off-by: Kentaro Makita \u003ck-makita@np.css.fujitsu.com\u003e\nCc: Neil Brown \u003cneilb@suse.de\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: David Chinner \u003cdgc@sgi.com\u003e\nCc: \"J.

As there\u0027s\nalready an sg iterator which iterates over sg entries themselves, name\nthis sg_mapping_iterator.\n\nSlightly edited description from the original implementation follows.\n\nIteration over a sg list is not that trivial when you take into\naccount that memory pages might have to be mapped before being used.\nUnfortunately, that means that some parts of the kernel restrict\nthemselves to directly accesible memory just to not have to deal with\nthe mess.\n\nThis patch adds a simple iterator system that allows any code to\neasily traverse an sg list and not have to deal with all the details.\nThe user can decide to consume part of the iteration.  Also, iteration\ncan be stopped and resumed later if releasing the kmap between\niteration steps is necessary.  These features are useful to implement\npiecemeal sg copying for interrupt drive PIO for example.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Pierre Ossman \u003cdrzeus@drzeus.cx\u003e\n"
