This situation can cause\nthe instance of __rcu_read_unlock() invoked from interrupt to do some\nof the processing that would otherwise have been carried out by the\ntask-level instance of __rcu_read_unlock(). When the interrupt-level\ninstance of __rcu_read_unlock() is called with a scheduler lock held\nfrom interrupt-entry/exit situations where in_irq() returns false,\ndeadlock can result.\n\nThis commit resolves these deadlocks by using negative values of\nthe per-task -\u003ercu_read_lock_nesting counter to indicate that an\ninstance of __rcu_read_unlock() is in flight, which in turn prevents\ninstances from interrupt handlers from doing any special processing.\nThis patch is inspired by Steven Rostedt\u0027s earlier patch that similarly\nmade __rcu_read_unlock() guard against interrupt-mediated recursion\n(see https://lkml.org/lkml/2011/7/15/326), but this commit refines\nSteven\u0027s approach to avoid the need for preemption disabling on the\n__rcu_read_unlock() fastpath and to also avoid the need for manipulating\na separate per-CPU variable.\n\nThis patch avoids need for preempt_disable() by instead using negative\nvalues of the per-task -\u003ercu_read_lock_nesting counter. Note that nested\nrcu_read_lock()/rcu_read_unlock() pairs are still permitted, but they will\nnever see -\u003ercu_read_lock_nesting go to zero, and will therefore never\ninvoke rcu_read_unlock_special(), thus preventing them from seeing the\nRCU_READ_UNLOCK_BLOCKED bit should it be set in -\u003ercu_read_unlock_special.\nThis patch also adds a check for -\u003ercu_read_unlock_special being negative\nin rcu_check_callbacks(), thus preventing the RCU_READ_UNLOCK_NEED_QS\nbit from being set should a scheduling-clock interrupt occur while\n__rcu_read_unlock() is exiting from an outermost RCU read-side critical\nsection.\n\nOf course, __rcu_read_unlock() can be preempted during the time that\n-\u003ercu_read_lock_nesting is negative. This could result in the setting\nof the RCU_READ_UNLOCK_BLOCKED bit after __rcu_read_unlock() checks it,\nand would also result it this task being queued on the corresponding\nrcu_node structure\u0027s blkd_tasks list. Therefore, some later RCU read-side\ncritical section would enter rcu_read_unlock_special() to clean up --\nwhich could result in deadlock if that critical section happened to be in\nthe scheduler where the runqueue or priority-inheritance locks were held.\n\nThis situation is dealt with by making rcu_preempt_note_context_switch()\ncheck for negative -\u003ercu_read_lock_nesting, thus refraining from\nqueuing the task (and from setting RCU_READ_UNLOCK_BLOCKED) if we are\nalready exiting from the outermost RCU read-side critical section (in\nother words, we really are no longer actually in that RCU read-side\ncritical section). In addition, rcu_preempt_note_context_switch()\ninvokes rcu_read_unlock_special() to carry out the cleanup in this case,\nwhich clears out the -\u003ercu_read_unlock_special bits and dequeues the task\n(if necessary), in turn avoiding needless delay of the current RCU grace\nperiod and needless RCU priority boosting.\n\nIt is still illegal to call rcu_read_unlock() while holding a scheduler\nlock if the prior RCU read-side critical section has ever had either\npreemption or irqs enabled. However, the common use case is legal,\nnamely where then entire RCU read-side critical section executes with\nirqs disabled, for example, when the scheduler lock is held across the\nentire lifetime of the RCU read-side critical section.\n\nSigned-off-by: Paul E.

These deadlocks would result from RCU incorrectly\nbelieving that the just-ended RCU read-side critical section had been\npreempted and/or boosted. If that RCU read-side critical section was\nexecuted with either rq or pi locks held, RCU\u0027s ensuing (incorrect)\ncalls to the scheduler would cause the scheduler to attempt to once\nagain acquire the rq and pi locks, resulting in deadlock. More complex\ndeadlock cycles are also possible, involving multiple rq and pi locks\nas well as locks from multiple rcu_node structures.\n\nThis commit fixes synchronization by creating -\u003ercu_boosted field in\ntask_struct that is accessed and modified only when holding the -\u003elock\nin the rcu_node structure on which the task is queued (on that rcu_node\nstructure\u0027s -\u003eblkd_tasks list). This results in tasks accessing only\ntheir own current-\u003ercu_read_unlock_special fields, making unsynchronized\naccess once again legal, and keeping the rcu_read_unlock() fastpath free\nof atomic instructions and memory barriers.\n\nThe reason that the rcu_read_unlock() fastpath does not need to access\nthe new current-\u003ercu_boosted field is that this new field cannot\nbe non-zero unless the RCU_READ_UNLOCK_BLOCKED bit is set in the\ncurrent-\u003ercu_read_unlock_special field.

This\nis expected behaviour. Unfortunately, if the highest zone is small, a\nproblem occurs.\n\nWhen balance_pgdat() returns, it may be at a lower classzone_idx than it\nstarted because the highest zone was unreclaimable. Before checking if it\nshould go to sleep though, it checks pgdat-\u003eclasszone_idx which when there\nis no other activity will be MAX_NR_ZONES-1. It interprets this as it has\nbeen woken up while reclaiming, skips scheduling and reclaims again. As\nthere is no useful reclaim work to do, it enters into a loop of shrinking\nslab consuming loads of CPU until the highest zone becomes reclaimable for\na long period of time.\n\nThere are two problems here. 1) If the returned classzone or order is\nlower, it\u0027ll continue reclaiming without scheduling. 2) if the highest\nzone was marked unreclaimable but balance_pgdat() returns immediately at\nDEF_PRIORITY, the new lower classzone is not communicated back to kswapd()\nfor sleeping.\n\nThis patch does two things that are related. If the end_zone is\nunreclaimable, this information is communicated back. Second, if the\nclasszone or order was reduced due to failing to reclaim, new information\nis not read from pgdat and instead an attempt is made to go to sleep.

Unfortunately, if the highest zone is small, a\nproblem occurs.\n\nThis seems to happen most with recent sandybridge laptops but it\u0027s\nprobably a co-incidence as some of these laptops just happen to have a\nsmall Normal zone. The reproduction case is almost always during copying\nlarge files that kswapd pegs at 100% CPU until the file is deleted or\ncache is dropped.\n\nThe problem is mostly down to sleeping_prematurely() keeping kswapd awake\nwhen the highest zone is small and unreclaimable and compounded by the\nfact we shrink slabs even when not shrinking zones causing a lot of time\nto be spent in shrinkers and a lot of memory to be reclaimed.\n\nPatch 1 corrects sleeping_prematurely to check the zones matching\n\tthe classzone_idx instead of all zones.\n\nPatch 2 avoids shrinking slab when we are not shrinking a zone.\n\nPatch 3 notes that sleeping_prematurely is checking lower zones against\n\ta high classzone which is not what allocators or balance_pgdat()\n\tis doing leading to an artifical belief that kswapd should be\n\tstill awake.\n\nPatch 4 notes that when balance_pgdat() gives up on a high zone that the\n\tdecision is not communicated to sleeping_prematurely()\n\nThis problem affects 2.6.38.8 for certain and is expected to affect 2.6.39\nand 3.0-rc4 as well.

This\nis expected behaviour.\n\nA problem occurs if the highest zone is small. balance_pgdat() only\nconsiders unreclaimable zones when priority is DEF_PRIORITY but\nsleeping_prematurely considers all zones. It\u0027s possible for this sequence\nto occur\n\n 1. kswapd wakes up and enters balance_pgdat()\n 2. At DEF_PRIORITY, marks highest zone unreclaimable\n 3. At DEF_PRIORITY-1, ignores highest zone setting end_zone\n 4. At DEF_PRIORITY-1, calls shrink_slab freeing memory from\n highest zone, clearing all_unreclaimable. Highest zone\n is still unbalanced\n 5. kswapd returns and calls sleeping_prematurely\n 6. sleeping_prematurely looks at *all* zones, not just the ones\n being considered by balance_pgdat. The highest small zone\n has all_unreclaimable cleared but the zone is not\n balanced. all_zones_ok is false so kswapd stays awake\n\nThis patch corrects the behaviour of sleeping_prematurely to check the\nzones balance_pgdat() checked.\n\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\nReported-by: Pádraig Brady \u003cP@draigBrady.com\u003e\nTested-by: Pádraig Brady \u003cP@draigBrady.com\u003e\nTested-by: Andrew Lutomirski \u003cluto@mit.edu\u003e\nAcked-by: Rik van Riel \u003criel@redhat.com\u003e\nReviewed-by: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "27739e694a3c34b5e371575d74e500d60111c689", "tree": "53daf18502775272d26174ccd96c8c2678806751", "parents": [ "fe0d42203cb5616eeff68b14576a0f7e2dd56625" ], "author": { "name": "Guenter Roeck", "email": "guenter.roeck@ericsson.com", "time": "Mon Jun 27 11:22:46 2011 -0700" }, "committer": { "name": "Guenter Roeck", "email": "guenter.roeck@ericsson.com", "time": "Fri Jul 08 17:52:59 2011 -0700" }, "message": "hwmon: (lm95241) Fix chip detection code\n\nThe LM95241 driver accepts every chip ID equal to or larger than 0xA4 as its\nown, and other chips such as LM95245 use chip IDs in the accepted ID range.\nThis results in false chip detection.\n\nFix problem by accepting only the known LM95241 chip ID.\n\nSigned-off-by: Guenter Roeck \u003cguenter.roeck@ericsson.com\u003e\nAcked-by: Jean Delvare \u003ckhali@linux-fr.org\u003e\nCc: stable@kernel.org # 2.6.30+\n" }, { "commit": "f483d3923dc3a6394c483e28ccb3fe700bdf399e", "tree": "ef487babd0ef104e1fa8323c23050d66096c0f3a", "parents": [ "a2fa83faf47b514ab947cea916d3691b66525073" ], "author": { "name": "Ram Pai", "email": "linuxram@us.ibm.com", "time": "Thu Jul 07 11:19:10 2011 -0700" }, "committer": { "name": "Jesse Barnes", "email": "jbarnes@virtuousgeek.org", "time": "Fri Jul 08 15:49:20 2011 -0700" }, "message": "PCI: conditional resource-reallocation through kernel parameter pci\u003drealloc\n \nMultiple attempts to dynamically reallocate pci resources have\nunfortunately lead to regressions.
