The only other time this should be set is\n when the task\u0027s quantum expires, in the timer interrupt - this is\n protected against because the rq lock is irq-safe.\n\n- If TIF_NEED_RESCHED is set, then we don\u0027t need to do anything. It\n won\u0027t get unset until the task get\u0027s schedule()d off.\n\n- If we are running on the same CPU as the task we resched, then set\n TIF_NEED_RESCHED and no further action is required.\n\n- If we are running on another CPU, and TIF_POLLING_NRFLAG is *not* set\n after TIF_NEED_RESCHED has been set, then we need to send an IPI.\n\nUsing these rules, we are able to remove the test and set operation in\nresched_task, and make clear the previously vague semantics of\nPOLLING_NRFLAG.\n\n* In idle routines:\n- Enter cpu_idle with preempt disabled.

This makes things a bit clearer\n (IMO), but haven\u0027t updated all architectures yet.\n\n- Many do a test and clear of TIF_NEED_RESCHED for some reason. According\n to the resched_task rules, this isn\u0027t needed (and actually breaks the\n assumption that TIF_NEED_RESCHED is only cleared with the runqueue lock\n held). So remove that. Generally one less locked memory op when switching\n to the idle thread.\n\n- Many idle routines clear TIF_POLLING_NRFLAG, and only set it in the inner\n most polling idle loops. The above resched_task semantics allow it to be\n set until before the last time need_resched() is checked before going into\n a halt requiring interrupt wakeup.\n\n Many idle routines simply never enter such a halt, and so POLLING_NRFLAG\n can be always left set, completely eliminating resched IPIs when rescheduling\n the idle task.\n\n POLLING_NRFLAG width can be increased, to reduce the chance of resched IPIs.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Con Kolivas \u003ckernel@kolivas.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "ede3d0fba99520f268067917b50858d788bc41da", "tree": "5c33dc43c22f0c2b17db2f118156384baa35cae8", "parents": [ "6dd4a85bb3ee0715415892c8b0f2a9bd08d31ca4" ], "author": { "name": "Con Kolivas", "email": "kernel@kolivas.org", "time": "Tue Nov 08 21:39:00 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Nov 09 07:56:32 2005 -0800" }, "message": "[PATCH] sched: consider migration thread with smp nice\n\nThe intermittent scheduling of the migration thread at ultra high priority\nmakes the smp nice handling see that runqueue as being heavily loaded.

Semantics:\n\n - when the last normal reference is dropped, all special ones are\n converted to normal ones and if there had been any, cleanup is done.\n - normal reference can be cloned into a special one\n - special reference can be converted to normal one; that\u0027s a no-op if\n we\u0027d already passed the point of no return (i.e. mntput() had\n converted special references to normal and started cleanup).\n\nThe way it works: e.g. starting process accounting converts the vfsmount\nreference pinned by the opened file into special one and turns it back\nto normal when it gets shut down; acct_auto_close() is done when no\nnormal references are left. That way it does *not* obstruct umount(2)\nand it silently gets turned off when the last normal reference to\nvfsmount is gone. Which is exactly what we want...\n\nThe same should be done by LSM module that holds some internal\nreferences to vfsmount and wants to shut them down on umount - it should\nmake them special and security_sb_umount_close() will be called exactly\nwhen the last normal reference to vfsmount is gone.\n\nquota handling is even simpler - we don\u0027t use normal file IO anymore, so\nthere\u0027s no need to hold vfsmounts at all.

This originated from a gdb\nbugreport (the fact gdb was segfaulting the task wasn\u0027t a kernel bug), but\nI just incidentally noticed the gdb bug triggered a real kernel bug as\nwell.\n\nMost threads hangs in exit_mm because the core_dumping is still going, the\ncore dumping hangs because the stopped task doesn\u0027t exit, the stopped task\ncan\u0027t wakeup because it has SIGNAL_GROUP_EXIT set, hence the deadlock.\n\nTo me it seems that the problem is that the force_sig_specific(SIGKILL) in\nzap_threads is a noop if the task has PF_PTRACED set (like in this case\nbecause gdb is attached). The __ptrace_unlink does nothing because the\nsignal-\u003eflags is set to SIGNAL_GROUP_EXIT|SIGNAL_STOP_DEQUEUED (verified).\n\nThe above info also shows that the stopped task hit a race and got the stop\nsignal (presumably by the ptrace_attach, only the attach, state is still\nTASK_STOPPED and gdb hangs waiting the core before it can set it to\nTASK_TRACED) after one of the thread invoked the core dump (it\u0027s the core\ndump that sets signal-\u003eflags to SIGNAL_GROUP_EXIT).\n\nSo beside the fact nobody would wakeup the task in __ptrace_unlink (the\nstate is _not_ TASK_TRACED), there\u0027s a secondary problem in the signal\nhandling code, where a task should ignore the ptrace-sigstops as long as\nSIGNAL_GROUP_EXIT is set (or the wakeup in __ptrace_unlink path wouldn\u0027t be\nenough).\n\nSo I attempted to make this patch that seems to fix the problem.

It does so within the context of the task,\nwithout any need to support low level external mempolicy manipulation.\n\nIf a system is not using cpusets, or if running on a system with just the\nroot (all-encompassing) cpuset, then this remap is a no-op. Only when a\ntask is moved between cpusets, or a cpusets memory placement is changed\ndoes the following apply. Otherwise, the main routine below,\nrebind_policy() is not even called.\n\nWhen mixing cpusets, scheduler affinity, and NUMA mempolicies, the\nessential role of cpusets is to place jobs (several related tasks) on a set\nof CPUs and Memory Nodes, the essential role of sched_setaffinity is to\nmanage a jobs processor placement within its allowed cpuset, and the\nessential role of NUMA mempolicy (mbind, set_mempolicy) is to manage a jobs\nmemory placement within its allowed cpuset.\n\nHowever, CPU affinity and NUMA memory placement are managed within the\nkernel using absolute system wide numbering, not cpuset relative numbering.\n\nThis is ok until a job is migrated to a different cpuset, or what\u0027s the\nsame, a jobs cpuset is moved to different CPUs and Memory Nodes.\n\nThen the CPU affinity and NUMA memory placement of the tasks in the job\nneed to be updated, to preserve their cpuset-relative position. This can\nbe done for CPU affinity using sched_setaffinity() from user code, as one\ntask can modify anothers CPU affinity. This cannot be done from an\nexternal task for NUMA memory placement, as that can only be modified in\nthe context of the task using it.\n\nHowever, it easy enough to remap a tasks NUMA mempolicy automatically when\na task is migrated, using the existing cpuset mechanism to trigger a\nrefresh of a tasks memory placement after its cpuset has changed. All that\nis needed is the old and new nodemask, and notice to the task that it needs\nto rebind its mempolicy. The tasks mems_allowed has the old mask, the\ntasks cpuset has the new mask, and the existing\ncpuset_update_current_mems_allowed() mechanism provides the notice. The\nbitmap/cpumask/nodemask remap operators provide the cpuset relative\ncalculations.\n\nThis patch leaves open a couple of issues:\n\n 1) Updating vma and shmfs/tmpfs/hugetlbfs memory policies:\n\n These mempolicies may reference nodes outside of those allowed to\n the current task by its cpuset. Tasks are migrated as part of jobs,\n which reside on what might be several cpusets in a subtree. When such\n a job is migrated, all NUMA memory policy references to nodes within\n that cpuset subtree should be translated, and references to any nodes\n outside that subtree should be left untouched. A future patch will\n provide the cpuset mechanism needed to mark such subtrees. With that\n patch, we will be able to correctly migrate these other memory policies\n across a job migration.\n\n 2) Updating cpuset, affinity and memory policies in user space:\n\n This is harder. Any placement state stored in user space using\n system-wide numbering will be invalidated across a migration. More\n work will be required to provide user code with a migration-safe means\n to manage its cpuset relative placement, while preserving the current\n API\u0027s that pass system wide numbers, not cpuset relative numbers across\n the kernel-user boundary.\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "18a19cb3047e454ee5ecbc35d7acf3f8e09e0466", "tree": "ad91d0024d886bdd207ba72e875e736e833de616", "parents": [ "053199edf54f685e7dea765b60d4d5e9070dadec" ], "author": { "name": "Paul Jackson", "email": "pj@sgi.com", "time": "Sun Oct 30 15:02:31 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 30 17:37:21 2005 -0800" }, "message": "[PATCH] cpusets: simple rename\n\nAdd support for renaming cpusets.

Changing\ncpusets involves several related checks and changes, which must be done\nwhile allowing read-only queries (to avoid the double trip), but while\nensuring nothing changes (holding off other would be modifiers.)\n\nThis overhaul of cpuset locking also makes careful use of task_lock() to\nguard access to the task-\u003ecpuset pointer, closing a couple of race\nconditions noticed while reading this code (thanks, Roman). I\u0027ve never\nseen these races fail in any use or test.\n\nSee further the comments in the code.\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "5aa15b5f27fc2c404530c6c8eabdb8437deb3163", "tree": "914f0b33f5190bd0183cde2e9f6da552d3d1d7aa", "parents": [ "f35f31d7ed0150f9865619f21b5050c91b46c03f" ], "author": { "name": "Paul Jackson", "email": "pj@sgi.com", "time": "Sun Oct 30 15:02:28 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 30 17:37:21 2005 -0800" }, "message": "[PATCH] cpusets: remove depth counted locking hack\n\nRemove a rather hackish depth counter on cpuset locking.
