(but it\u0027s nothing)\n\nB) Current futex code doesn\u0027t handle zero page properly.\n\nRead mode get_user_pages() can return zero page, but current\nfutex code doesn\u0027t handle it at all. Then, zero page makes\ninfinite loop internally.\n\nThe solution is to use write mode get_user_page() always for\npage lookup. It prevents the lookup of both file page of private\nmappings and zero page.\n\nPerformance concerns:\n\nProbaly very little, because glibc always initialize variables\nfor futex before to call futex(). It means glibc users never see\nthe overhead of this patch.\n\nCompatibility concerns:\n\nThis patch has few compatibility issues. After this patch,\nFUTEX_WAIT require writable access to futex variables (read-only\nmappings makes EFAULT).

generates the BUG_ON, which is caused\nwhen pidlist_array_load() calls cgroup_pidlist_find():\n\n(1) if a matching cgroup_pidlist is found, it down_write\u0027s the mutex of the\n pre-existing cgroup_pidlist, and increments its use_count.\n(2) if no matching cgroup_pidlist is found, then a new one is allocated, it\n down_write\u0027s its mutex, and the use_count is set to 0.\n(3) the matching, or new, cgroup_pidlist gets returned back to pidlist_array_load(),\n which increments its use_count -- regardless whether new or pre-existing --\n and up_write\u0027s the mutex.\n\nSo if a

Only 17 files in the current 2.6.31-rc5 used it.\nFIFO\u0027s are like list\u0027s a very basic thing and a kfifo API which handles\nthe most use case would save a lot of development time and memory\nresources.\n\nI think this are the reasons why kfifo is not in use:\n\n - The API is to simple, important functions are missing\n - A fifo can be only allocated dynamically\n - There is a requirement of a spinlock whether you need it or not\n - There is no support for data records inside a fifo\n\nSo I decided to extend the kfifo in a more generic way without blowing up\nthe API to much. The new API has the following benefits:\n\n - Generic usage: For kernel internal use and/or device driver.\n - Provide an API for the most use case.\n - Slim API: The whole API provides 25 functions.\n - Linux style habit.\n - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros\n - Direct copy_to_user from the fifo and copy_from_user into the fifo.\n - The kfifo itself is an in place member of the using data structure, this save an\n indirection access and does not waste the kernel allocator.\n - Lockless access: if only one reader and one writer is active on the fifo,\n which is the common use case, no additional locking is necessary.\n - Remove spinlock - give the user the freedom of choice what kind of locking to use if\n one is required.\n - Ability to handle records. Three type of records are supported:\n - Variable length records between 0-255 bytes, with a record size\n field of 1 bytes.\n - Variable length records between 0-65535 bytes, with a record size\n field of 2 bytes.\n - Fixed size records, which no record size field.\n - Preserve memory resource.\n - Performance!\n - Easy to use!\n\nThis patch:\n\nSince most users want to have the kfifo as part of another object,\nreorganize the code to allow including struct kfifo in another data\nstructure. This requires changing the kfifo_alloc and kfifo_init\nprototypes so that we pass an existing kfifo pointer into them.

Quoting John:\n\n \"Petr Titěra reported an issue where he saw odd atime regressions with\n 2.6.33 where there were a full second worth of nanoseconds in the\n nanoseconds field.\n\n He also reviewed the time code and narrowed down the problem: unhandled\n overflow of the nanosecond field caused by rounding up the\n sub-nanosecond accumulated time.\n\n Details:\n\n * At the end of update_wall_time(), we currently round up the\n sub-nanosecond portion of accumulated time when storing it into xtime.\n This was added to avoid time inconsistencies caused when the\n sub-nanosecond portion was truncated when storing into xtime.\n Unfortunately we don\u0027t handle the possible second overflow caused by\n that rounding.\n\n * Previously the xtime_cache code hid this overflow by normalizing the\n xtime value when storing into the xtime_cache.\n\n * We could try to handle the second overflow after the rounding up, but\n since this affects the timekeeping\u0027s internal state, this would further\n complicate the next accumulation cycle, causing small errors in ntp\n steering. As much as I\u0027d like to get rid of it, the xtime_cache code is\n known to work.\n\n * The correct fix is really to include the sub-nanosecond portion in the\n timekeeping accessor function, so we don\u0027t need to round up at during\n accumulation. This would greatly simplify the accumulation code.\n Unfortunately, we can\u0027t do this safely until the last three\n non-GENERIC_TIME arches (sparc32, arm, cris) are converted (those\n patches are in -mm) and we kill off the spots where arches set xtime\n directly. This is all 2.6.34 material, so I think reverting the\n xtime_cache change is the best approach for now.\n\n Many thanks to Petr for both reporting and finding the issue!\"\n\nReported-by: Petr Titěra \u003cP.Titera@century.cz\u003e\nRequested-by: john stultz \u003cjohnstul@us.ibm.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5300990c0370e804e49d9a59d928c5d53fb73487", "tree": "08ed922afd172662039c082ec9e9410070f4afe8", "parents": [ "482928d59db668b8d82a48717f78986d8cea72e9" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Sat Dec 19 10:15:07 2009 -0500" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Dec 22 12:27:34 2009 -0500" }, "message": "Sanitize f_flags helpers\n\n* pull ACC_MODE to fs.h; we have several copies all over the place\n* nightmarish expression calculating f_mode by f_flags deserves a helper\ntoo (OPEN_FMODE(flags))\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "628ff7c1d8d8466a5ad8078bd0206a130f8b8a51", "tree": "cc7ab0c90849be38e200fc6ff6a3a09e3caf0405", "parents": [ "ed2617585f39dd12fae38c657bba68b9779ea10d" ], "author": { "name": "Roland Dreier", "email": "rdreier@cisco.com", "time": "Fri Dec 18 09:41:24 2009 -0800" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Dec 22 12:27:34 2009 -0500" }, "message": "anonfd: Allow making anon files read-only\n\nIt seems a couple places such as arch/ia64/kernel/perfmon.c and\ndrivers/infiniband/core/uverbs_main.c could use anon_inode_getfile()\ninstead of a private pseudo-fs + alloc_file(), if only there were a way\nto get a read-only file.

set_task_cpu()\n\nIn order to remove the cfs_rq dependency from set_task_cpu() we\nneed to ensure the task is cfs_rq invariant for all callsites.\n\nThe simple approach is to substract cfs_rq-\u003emin_vruntime from\nse-\u003evruntime on dequeue, and add cfs_rq-\u003emin_vruntime on\nenqueue.\n\nHowever, this has the downside of breaking FAIR_SLEEPERS since\nwe loose the old vruntime as we only maintain the relative\nposition.\n\nTo solve this, we observe that we only migrate runnable tasks,\nwe do this using deactivate_task(.sleep\u003d0) and\nactivate_task(.wakeup\u003d0), therefore we can restrain the\nmin_vruntime invariance to that state.\n\nThe only other case is wakeup balancing, since we want to\nmaintain the old vruntime we cannot make it relative on dequeue,\nbut since we don\u0027t migrate inactive tasks, we can do so right\nbefore we activate it again.\n\nThis is where we need the new pre-wakeup hook, we need to call\nthis while still holding the old rq-\u003elock. We could fold it into\n-\u003eselect_task_rq(), but since that has multiple callsites and\nwould obfuscate the locking requirements, that seems like a\nfudge.\n\nThis leaves the fork() case, simply make sure that -\u003etask_fork()\nleaves the -\u003evruntime in a relative state.\n\nThis covers all cases where set_task_cpu() gets called, and\nensures it sees a relative vruntime.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nLKML-Reference:

Fix this by moving the de-activation into\n_cpu_down after doing the initial checks.\n\nRemove the synchronize_sched() calls and rely on those implied\nby rebuilding the sched domains using the new mask.\n\nReported-by: Sachin Sant \u003csachinp@in.ibm.com\u003e\nSigned-off-by: Xiaotian Feng \u003cdfeng@redhat.com\u003e\nTested-by: Sachin Sant \u003csachinp@in.ibm.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nLKML-Reference: \u003c20091216170517.500272612@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "ee1156c11a1121e118b0a7f2dec240f0d421b1fd", "tree": "b8771cc5a9758af9d7410fc519227c036c222130", "parents": [ "b9f8fcd55bbdb037e5332dbdb7b494f0b70861ac", "8bea8672edfca7ec5f661cafb218f1205863b343" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Dec 16 18:33:49 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Dec 16 18:33:49 2009 +0100" }, "message": "Merge branch \u0027linus\u0027 into sched/urgent\n\nConflicts:\n\tkernel/sched_idletask.c\n\nMerge reason: resolve the conflicts, pick up latest changes.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "f4c4176f21533e22bcc292030da72bcfa105f5b8", "tree": "9e4376f5ff4dc3fb0f333faca94f219570df9af8", "parents": [ "9b33827de63539c7c3314ddf890fb216e4acf3d8" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Wed Dec 16 17:55:54 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Dec 16 18:30:11 2009 +0100" }, "message": "perf events: Allow per-task-per-cpu counters\n\nIn order to allow for per-task-per-cpu counters, useful for\nscalability when profiling task hierarchies, we allow installing\nevents with event-\u003ecpu !\u003d -1 in task contexts.\n\n__perf_event_sched_in() already skips events where -\u003ecpu\nmis-matches the current cpu, fix up __perf_install_in_context()\nand __perf_event_enable() to also respect this filter.\n\nThis does lead to vary hard to interpret enabled/running times\nfor such counters, but I don\u0027t see a simple solution for that.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: fweisbec@gmail.com\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nLKML-Reference: \u003c20091216165904.831451147@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "06a7f711246b081afc21fff859f1003f1f2a0fbc", "tree": "aece49693ad751923ce71387201d3c3e6214e335", "parents": [ "1f2c19f8c959c1d0ccd3e33b1f480593b66d95dd" ], "author": { "name": "Amerigo Wang", "email": "amwang@redhat.com", "time": "Tue Dec 15 16:47:46 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Dec 16 07:20:13 2009 -0800" }, "message": "kexec: premit reduction of the reserved memory size\n\nImplement shrinking the reserved memory for crash kernel, if it is more\nthan enough.\n\nFor example, if you have already reserved 128M, now you just want 100M,\nyou can do:\n\n# echo $((100*1024*1024)) \u003e /sys/kernel/kexec_crash_size\n\nNote, you can only do this before loading the crash kernel.\n\nSigned-off-by: WANG Cong \u003camwang@redhat.com\u003e\nCc: Neil Horman \u003cnhorman@redhat.com\u003e\nAcked-by: Eric W.
