      "message": "kthread: implement probe_kthread_data()\n\nOne of the problems that arise when converting dedicated custom threadpool\nto workqueue is that the shared worker pool used by workqueue anonimizes\neach worker making it more difficult to identify what the worker was doing\non which target from the output of sysrq-t or debug dump from oops, BUG()\nand friends.\n\nFor example, after writeback is converted to use workqueue instead of\npriviate thread pool, there\u0027s no easy to tell which backing device a\nwriteback work item was working on at the time of task dump, which,\naccording to our writeback brethren, is important in tracking down issues\nwith a lot of mounted file systems on a lot of different devices.\n\nThis patchset implements a way for a work function to mark its execution\ninstance so that task dump of the worker task includes information to\nindicate what the work item was doing.\n\nAn example WARN dump would look like the following.\n\n WARNING: at fs/fs-writeback.c:1015 bdi_writeback_workfn+0x2b4/0x3c0()\n Modules linked in:\n CPU: 0 Pid: 28 Comm: kworker/u18:0 Not tainted 3.9.0-rc1-work+ #24\n Hardware name: empty empty/S3992, BIOS 080011  10/26/2007\n Workqueue: writeback bdi_writeback_workfn (flush-8:16)\n  ffffffff820a3a98 ffff88015b927cb8 ffffffff81c61855 ffff88015b927cf8\n  ffffffff8108f500 0000000000000000 ffff88007a171948 ffff88007a1716b0\n  ffff88015b49df00 ffff88015b8d3940 0000000000000000 ffff88015b927d08\n Call Trace:\n  [\u003cffffffff81c61855\u003e] dump_stack+0x19/0x1b\n  [\u003cffffffff8108f500\u003e] warn_slowpath_common+0x70/0xa0\n  ...\n\nThis patch:\n\nImplement probe_kthread_data() which returns kthread_data if accessible.\nThe function is equivalent to kthread_data() except that the specified\n@task may not be a kthread or its vfork_done is already cleared rendering\nstruct kthread inaccessible.

      "message": "Merge branch \u0027for-3.10\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq\n\nPull workqueue updates from Tejun Heo:\n \"A lot of activities on workqueue side this time.  The changes achieve\n  the followings.\n\n   - WQ_UNBOUND workqueues - the workqueues which are per-cpu - are\n     updated to be able to interface with multiple backend worker pools.\n     This involved a lot of churning but the end result seems actually\n     neater as unbound workqueues are now a lot closer to per-cpu ones.\n\n   - The ability to interface with multiple backend worker pools are\n     used to implement unbound workqueues with custom attributes.\n     Currently the supported attributes are the nice level and CPU\n     affinity.  It may be expanded to include cgroup association in\n     future.  The attributes can be specified either by calling\n     apply_workqueue_attrs() or through /sys/bus/workqueue/WQ_NAME/* if\n     the workqueue in question is exported through sysfs.\n\n     The backend worker pools are keyed by the actual attributes and\n     shared by any workqueues which share the same attributes.  When\n     attributes of a workqueue are changed, the workqueue binds to the\n     worker pool with the specified attributes while leaving the work\n     items which are already executing in its previous worker pools\n     alone.\n\n     This allows converting custom worker pool implementations which\n     want worker attribute tuning to use workqueues.  The writeback pool\n     is already converted in block tree and there are a couple others\n     are likely to follow including btrfs io workers.\n\n   - WQ_UNBOUND\u0027s ability to bind to multiple worker pools is also used\n     to make it NUMA-aware.  Because there\u0027s no association between work\n     item issuer and the specific worker assigned to execute it, before\n     this change, using unbound workqueue led to unnecessary cross-node\n     bouncing and it couldn\u0027t be helped by autonuma as it requires tasks\n     to have implicit node affinity and workers are assigned randomly.\n\n     After these changes, an unbound workqueue now binds to multiple\n     NUMA-affine worker pools so that queued work items are executed in\n     the same node.  This is turned on by default but can be disabled\n     system-wide or for individual workqueues.\n\n     Crypto was requesting NUMA affinity as encrypting data across\n     different nodes can contribute noticeable overhead and doing it\n     per-cpu was too limiting for certain cases and IO throughput could\n     be bottlenecked by one CPU being fully occupied while others have\n     idle cycles.\n\n  While the new features required a lot of changes including\n  restructuring locking, it didn\u0027t complicate the execution paths much.\n  The unbound workqueue handling is now closer to per-cpu ones and the\n  new features are implemented by simply associating a workqueue with\n  different sets of backend worker pools without changing queue,\n  execution or flush paths.\n\n  As such, even though the amount of change is very high, I feel\n  relatively safe in that it isn\u0027t likely to cause subtle issues with\n  basic correctness of work item execution and handling.  If something\n  is wrong, it\u0027s likely to show up as being associated with worker pools\n  with the wrong attributes or OOPS while workqueue attributes are being\n  changed or during CPU hotplug.\n\n  While this creates more backend worker pools, it doesn\u0027t add too many\n  more workers unless, of course, there are many workqueues with unique\n  combinations of attributes.  Assuming everything else is the same,\n  NUMA awareness costs an extra worker pool per NUMA node with online\n  CPUs.\n\n  There are also a couple things which are being routed outside the\n  workqueue tree.\n\n   - block tree pulled in workqueue for-3.10 so that writeback worker\n     pool can be converted to unbound workqueue with sysfs control\n     exposed.  This simplifies the code, makes writeback workers\n     NUMA-aware and allows tuning nice level and CPU affinity via sysfs.\n\n   - The conversion to workqueue means that there\u0027s no 1:1 association\n     between a specific worker, which makes writeback folks unhappy as\n     they want to be able to tell which filesystem caused a problem from\n     backtrace on systems with many filesystems mounted.  This is\n     resolved by allowing work items to set debug info string which is\n     printed when the task is dumped.  As this change involves unifying\n     implementations of dump_stack() and friends in arch codes, it\u0027s\n     being routed through Andrew\u0027s -mm tree.\"\n\n* \u0027for-3.10\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (84 commits)\n  workqueue: use kmem_cache_free() instead of kfree()\n  workqueue: avoid false negative WARN_ON() in destroy_workqueue()\n  workqueue: update sysfs interface to reflect NUMA awareness and a kernel param to disable NUMA affinity\n  workqueue: implement NUMA affinity for unbound workqueues\n  workqueue: introduce put_pwq_unlocked()\n  workqueue: introduce numa_pwq_tbl_install()\n  workqueue: use NUMA-aware allocation for pool_workqueues\n  workqueue: break init_and_link_pwq() into two functions and introduce alloc_unbound_pwq()\n  workqueue: map an unbound workqueues to multiple per-node pool_workqueues\n  workqueue: move hot fields of workqueue_struct to the end\n  workqueue: make workqueue-\u003ename[] fixed len\n  workqueue: add workqueue-\u003eunbound_attrs\n  workqueue: determine NUMA node of workers accourding to the allowed cpumask\n  workqueue: drop \u0027H\u0027 from kworker names of unbound worker pools\n  workqueue: add wq_numa_tbl_len and wq_numa_possible_cpumask[]\n  workqueue: move pwq_pool_locking outside of get/put_unbound_pool()\n  workqueue: fix memory leak in apply_workqueue_attrs()\n  workqueue: fix unbound workqueue attrs hashing / comparison\n  workqueue: fix race condition in unbound workqueue free path\n  workqueue: remove pwq_lock which is no longer used\n  ...\n"

Because the memory policy is applied in the process\u0027s\ncontext originally.  After applying this patch, one task directly\nmanipulates anothers mems_allowed, and we use alloc_lock in the\ntask_struct to protect mems_allowed and memory policy of the task.\n\nBut in the fast path, we didn\u0027t use lock to protect them, because adding a\nlock may lead to performance regression.  But if we don\u0027t add a lock,the\ntask might see no nodes when changing cpuset\u0027s mems_allowed to some\nnon-overlapping set.  In order to avoid it, we set all new allowed nodes,\nthen clear newly disallowed ones.\n\n[lee.schermerhorn@hp.com:\n  The rework of mpol_new() to extract the adjusting of the node mask to\n  apply cpuset and mpol flags \"context\" breaks set_mempolicy() and mbind()\n  with MPOL_PREFERRED and a NULL nodemask--i.e., explicit local\n  allocation.  Fix this by adding the check for MPOL_PREFERRED and empty\n  node mask to mpol_new_mpolicy().\n\n  Remove the now unneeded \u0027nodes \u003d NULL\u0027 from mpol_new().\n\n  Note that mpol_new_mempolicy() is always called with a non-NULL\n  \u0027nodes\u0027 parameter now that it has been removed from mpol_new().\n  Therefore, we don\u0027t need to test nodes for NULL before testing it for\n  \u0027empty\u0027.  However, just to be extra paranoid, add a VM_BUG_ON() to\n  verify this assumption.]\n[lee.schermerhorn@hp.com:\n\n  I don\u0027t think the function name \u0027mpol_new_mempolicy\u0027 is descriptive\n  enough to differentiate it from mpol_new().\n\n  This function applies cpuset set context, usually constraining nodes\n  to those allowed by the cpuset.  However, when the \u0027RELATIVE_NODES flag\n  is set, it also translates the nodes.  So I settled on\n  \u0027mpol_set_nodemask()\u0027, because the comment block for mpol_new() mentions\n  that we need to call this function to \"set nodes\".\n\n  Some additional minor line length, whitespace and typo cleanup.]\nSigned-off-by: Miao Xie \u003cmiaox@cn.fujitsu.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nCc: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Tools like LTTng can\nexport this scheduler information along with instrumentation of the rest\nof the kernel activity to perform post-mortem analysis on the scheduler\nactivity.\n\nAbout the performance impact of tracepoints (which is comparable to\nmarkers), even without immediate values optimizations, tests done by\nHideo Aoki on ia64 show no regression. His test case was using hackbench\non a kernel where scheduler instrumentation (about 5 events in code\nscheduler code) was added. See the \"Tracepoints\" patch header for\nperformance result detail.\n\nChangelog :\n\n- Change instrumentation location and parameter to match ftrace\n  instrumentation, previously done with kernel markers.\n\n[ mingo@elte.hu: conflict resolutions ]\nSigned-off-by: Mathieu Desnoyers \u003cmathieu.desnoyers@polymtl.ca\u003e\nAcked-by: \u0027Peter Zijlstra\u0027 \u003cpeterz@infradead.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "change kernel threads to ignore signals instead of blocking them\n\nCurrently kernel threads use sigprocmask(SIG_BLOCK) to protect against\nsignals.  This doesn\u0027t prevent the signal delivery, this only blocks\nsignal_wake_up().  Every \"killall -33 kthreadd\" means a \"struct siginfo\"\nleak.\n\nChange kthreadd_setup() to set all handlers to SIG_IGN instead of blocking\nthem (make a new helper ignore_signals() for that).  If the kernel thread\nneeds some signal, it should use allow_signal() anyway, and in that case it\nshould not use CLONE_SIGHAND.\n\nNote that we can\u0027t change daemonize() (should die!) in the same way,\nbecause it can be used along with CLONE_SIGHAND.  This means that\nallow_signal() still should unblock the signal to work correctly with\ndaemonize()ed threads.\n\nHowever, disallow_signal() doesn\u0027t block the signal any longer but ignores\nit.\n\nNOTE: with or without this patch the kernel threads are not protected from\nhandle_stop_signal(), this seems harmless, but not good.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: \"Eric W.

This governs auto-release of the structure upon execution.\n\nOrdinarily, the work queue executor would release the work_struct for further\nscheduling or deallocation by clearing the pending bit prior to jumping to the\nwork function.  This means that, unless the driver makes some guarantee itself\nthat the work_struct won\u0027t go away, the work function may not access anything\nelse in the work_struct or its container lest they be deallocated..  This is a\nproblem if the auxiliary data is taken away (as done by the last patch).\n\nHowever, if the pending bit is *not* cleared before jumping to the work\nfunction, then the work function *may* access the work_struct and its container\nwith no problems.  But then the work function must itself release the\nwork_struct by calling work_release().\n\nIn most cases, automatic release is fine, so this is the default.
