With struct pid being dynamically\nallocated meant we could create the hash table entry when the pid was\nallocated and free the hash table entry when the pid was freed. Instead of\nplaying with the hash lists when ever a process would attach or detach to a\nprocess.\n\nFor myself the fact that it gave what my previous task_ref patch gave for free\nwith simpler code was a big win. The problem is that if you hold a reference\nto struct task_struct you lock in 10K of low memory. If you do that in a user\ncontrollable way like /proc does, with an unprivileged but hostile user space\napplication with typical resource limits of 1000 fds and 100 processes I can\ntrigger the OOM killer by consuming all of low memory with task structs, on a\nmachine wight 1GB of low memory.\n\nIf I instead hold a reference to struct pid which holds a pointer to my\ntask_struct, I don\u0027t suffer from that problem because struct pid is 2 orders\nof magnitude smaller. In fact struct pid is small enough that most other\nkernel data structures dwarf it, so simply limiting the number of referring\ndata structures is enough to prevent exhaustion of low memory.\n\nThis splits the current struct pid into two structures, struct pid and struct\npid_link, and reduces our number of hash tables from PIDTYPE_MAX to just one.\nstruct pid_link is the per process linkage into the hash tables and lives in\nstruct task_struct. struct pid is given an indepedent lifetime, and holds\npointers to each of the pid types.\n\nThe independent life of struct pid simplifies attach_pid, and detach_pid,\nbecause we are always manipulating the list of pids and not the hash table.\nIn addition in giving struct pid an indpendent life it makes the concept much\nmore powerful.\n\nKernel data structures can now embed a struct pid * instead of a pid_t and\nnot suffer from pid wrap around problems or from keeping unnecessarily\nlarge amounts of memory allocated.\n\nSigned-off-by: Eric W.

I think someone finally implemented atomic_inc_not_zero(\u0026count) to\nautomate the common case. Unfortunately this means you must special case the\nrcu access case.\n\nWhen data structures are only visible via rcu in a manner that is not\ndetermined by the reference count on the object (i.e. tasks are visible until\ntheir zombies are reaped) there is a much simpler technique we can employ.\nSimply delaying the decrement of the reference count until the rcu interval is\nover.\n\nWhat that means is that the proc code that looks up a task and later\nwants to sleep can now do:\n\nrcu_read_lock();\ntask \u003d find_task_by_pid(some_pid);\nif (task) {\n\tget_task_struct(task);\n}\nrcu_read_unlock();\n\nThe effect on the rest of the kernel is that put_task_struct becomes cheaper\nand immediate, and in the case where the task has been reaped it frees the\ntask immediate instead of unnecessarily waiting an until the rcu interval is\nover.\n\nCleanup of task_struct does not happen when its reference count drops to\nzero, instead cleanup happens when release_task is called. Tasks can only\nbe looked up via rcu before release_task is called. All rcu protected\nmembers of task_struct are freed by release_task.\n\nTherefore we can move call_rcu from put_task_struct into release_task. And\nwe can modify release_task to not immediately release the reference count\nbut instead have it call put_task_struct from the function it gives to\ncall_rcu.\n\nThe end result:\n\n- get_task_struct is safe in an rcu context where we have just looked\n up the task.\n\n- put_task_struct() simplifies into its old pre rcu self.\n\nThis reorganization also makes put_task_struct uncallable from modules as\nit is not exported but it does not appear to be called from any modules so\nthis should not be an issue, and is trivially fixed.\n\nSigned-off-by: Eric W.

On handheld or embedded devices\nthey\u0027re an important part of an often limited user interface. Both users and\ndevelopers want to be able to control and configure what the LED does and the\nnumber of different things they\u0027d potentially want the LED to show is large.\n\nA subsystem is needed to try and provide all this different functionality in\nan architecture independent, simple but complete, generic and scalable manner.\n\nThe alternative is for everyone to implement just what they need hidden away\nin different corners of the kernel source tree and to provide an inconsistent\ninterface to userspace.\n\nOther Implementations\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nI\u0027m aware of the existing arm led implementation. Currently the new subsystem\nand the arm code can coexist quite happily. Its up to the arm community to\ndecide whether this new interface is acceptable to them. As far as I can see,\nthe new interface can do everything the existing arm implementation can with\nthe advantage that the new code is architecture independent and much more\ngeneric, configurable and scalable.\n\nI\u0027m prepared to make the conversion to the LED subsystem (or assist with it)\nif appropriate.\n\nImplementation Details\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nI\u0027ve stripped a lot of code out of John\u0027s original LED class. Colours were\nremoved as LED colour is now part of the device name. Multiple colours are to\nbe handled as multiple led devices. This means you get full control over each\ncolour. I also removed the LED hardware timer code as the generic timer isn\u0027t\ngoing to add much overhead and is just as useful. I also decided to have the\nLED core track the current LED status (to ease suspend/resume handling)\nremoving the need for brightness_get implementations in the LED drivers.\n\nAn underlying design philosophy is simplicity. The aim is to keep a small\namount of code giving as much functionality as possible.\n\nThe major new idea is the led \"trigger\". A trigger is a source of led events.\n Triggers can either be simple or complex. A simple trigger isn\u0027t\nconfigurable and is designed to slot into existing subsystems with minimal\nadditional code. Examples are the ide-disk, nand-disk and zaurus-charging\ntriggers. With leds disabled, the code optimises away. Examples are\nnand-disk and ide-disk.\n\nComplex triggers whilst available to all LEDs have LED specific parameters and\nwork on a per LED basis. The timer trigger is an example.\n\nYou can change triggers in a similar manner to the way an IO scheduler is\nchosen (via /sys/class/leds/somedevice/trigger).\n\nSo far there are only a handful of examples but it should easy to add further\nLED triggers without too much interference into other subsystems.\n\nKnown Issues\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nThe LED Trigger core cannot be a module as the simple trigger functions would\ncause nightmare dependency issues. I see this as a minor issue compared to\nthe benefits the simple trigger functionality brings. The rest of the LED\nsubsystem can be modular.\n\nSome leds can be programmed to flash in hardware. As this isn\u0027t a generic LED\ndevice property, I think this should be exported as a device specific sysfs\nattribute rather than part of the class if this functionality is required (eg.\n to keep the led flashing whilst the device is suspended).\n\nFuture Development\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nAt the moment, a trigger can\u0027t be created specifically for a single LED.\nThere are a number of cases where a trigger might only be mappable to a\nparticular LED. The addition of triggers provided by the LED driver should\ncover this option and be possible to add without breaking the current\ninterface.\n\nA CPU activity trigger similar to that found in the arm led implementation\nshould be trivial to add.\n\nThis patch:\n\nAdd some brief documentation of the design decisions behind the LED class and\nhow it appears to users.\n\nSigned-off-by: Richard Purdie \u003crpurdie@rpsys.net\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "7529c301165079d0f149d0e54724829e602f8fc0", "tree": "56e0ae4caed9675f230e63274cd3c9258eaaca44", "parents": [ "0ca07731e495584bd84dca15a0f065470d594ec4" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Fri Mar 31 02:30:59 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Mar 31 12:18:56 2006 -0800" }, "message": "[PATCH] modules: permit Dual-MIT/GPL licenses\n\nOne of the LEDs driver files wants to use this.\n\nProbably drivers/mtd/maps/ipaq-flash.c wants to convert as well - right now\nit\u0027ll be tainting the kernel.\n\nCc: David Woodhouse \u003cdwmw2@infradead.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: John Bowler \u003cjbowler@acm.org\u003e\nCc: \"\u0027Richard Purdie\u0027\" \u003crpurdie@rpsys.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0ca07731e495584bd84dca15a0f065470d594ec4", "tree": "d043e8b64b43361051e1e6b40ee37382591825df", "parents": [ "d32af0fe11b1618572389723e93cf33a4cc11c81" ], "author": { "name": "Rafael J.

The\nstart_time of the first thread in the process (group_leader) should be\nreduced from uptime to calculate etime and btime correctly.\n\n ---- do_acct_process() in kernel/acct.c:\n /* calculate run_time in nsec*/\n do_posix_clock_monotonic_gettime(\u0026uptime);\n run_time \u003d (u64)uptime.tv_sec*NSEC_PER_SEC + uptime.tv_nsec;\n run_time -\u003d (u64)current-\u003estart_time.tv_sec*NSEC_PER_SEC\n + current-\u003estart_time.tv_nsec;\n ----\n\nThe following section calculates stime and utime of the process.\nBut it might count the utime and stime of the group_leader duplicatly\nand ignore the utime and stime of the thread dies last, when one or\nmore threads remain after group_leader dead.\nThe ac_utime should be calculated as the sum of the signal-\u003eutime\nand utime of the thread dies last. The ac_stime should be done also.\n\n ---- do_acct_process() in kernel/acct.c:\n jiffies \u003d cputime_to_jiffies(cputime_add(current-\u003egroup_leader-\u003eutime,\n current-\u003esignal-\u003eutime));\n ac.ac_utime \u003d encode_comp_t(jiffies_to_AHZ(jiffies));\n jiffies \u003d cputime_to_jiffies(cputime_add(current-\u003egroup_leader-\u003estime,\n current-\u003esignal-\u003estime));\n ac.ac_stime \u003d encode_comp_t(jiffies_to_AHZ(jiffies));\n ----\n\nThe part of the minflt/majflt calculation has same problem.\nThis patch solves those problems, I think.\n\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f79e2abb9bd452d97295f34376dedbec9686b986", "tree": "56b9998caa11983556e842fb9a8143d86d765fa3", "parents": [ "d6dfd1310d3562698fd7c3c086f6c239f96394ac" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Fri Mar 31 02:30:42 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Mar 31 12:18:54 2006 -0800" }, "message": "[PATCH] sys_sync_file_range()\n\nRemove the recently-added LINUX_FADV_ASYNC_WRITE and LINUX_FADV_WRITE_WAIT\nfadvise() additions, do it in a new sys_sync_file_range() syscall instead.\nReasons:\n\n- It\u0027s more flexible. 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. I can skip the -\u003efsync call for\nNFS_DATA_SYNC which is hopefully the more common.\"\n\nNote: the `async\u0027 writeout mode SYNC_FILE_RANGE_WRITE will turn synchronous if\nthe queue is congested. This is trivial to fix: add a new flag bit, set\nwbc-\u003enonblocking. But I\u0027m not sure that we want to expose implementation\ndetails down to that level.\n\nNote: it\u0027s notable that we can sync an fd which wasn\u0027t opened for writing.\nSame with fsync() and fdatasync()).\n\nNote: the code takes some care to handle attempts to sync file contents\noutside the 16TB offset on 32-bit machines. It makes such attempts appear to\nsucceed, for best 32-bit/64-bit compatibility.
