too_many_isolated() returns true while performing\ndirect reclaim we can end up waiting for other threads to complete their\ndirect reclaim. If those threads are allowed to enter the FS or IO to\nfree memory, but this thread is not, then it is possible that those\nthreads will be waiting on this thread and so we get a circular deadlock.\n\nsome task enters direct reclaim with GFP_KERNEL\n \u003d\u003e too_many_isolated() false\n \u003d\u003e vmscan and run into dirty pages\n \u003d\u003e pageout()\n \u003d\u003e take some FS lock\n \u003d\u003e fs/block code does GFP_NOIO allocation\n \u003d\u003e enter direct reclaim again\n \u003d\u003e too_many_isolated() true\n \u003d\u003e waiting for others to progress, however the other\n tasks may be circular waiting for the FS lock..\n\nThe fix is to let !__GFP_IO and !__GFP_FS direct reclaims enjoy higher\npriority than normal ones, by lowering the throttle threshold for the\nlatter.\n\nAllowing ~1/8 isolated pages in normal is large enough. For example, for\na 1GB LRU list, that\u0027s ~128MB isolated pages, or 1k blocked tasks (each\nisolates 32 4KB pages), or 64 blocked tasks per logical CPU (assuming 16\nlogical CPUs per NUMA node). So it\u0027s not likely some CPU goes idle\nwaiting (when it could make progress) because of this limit: there are\nmuch more sleeping reclaim tasks than the number of CPU, so the task may\nwell be blocked by some low level queue/lock anyway.\n\nNow !GFP_IOFS reclaims won\u0027t be waiting for GFP_IOFS reclaims to progress.\n They will be blocked only when there are too many concurrent !GFP_IOFS\nreclaims, however that\u0027s very unlikely because the IO-less direct reclaims\nis able to progress much more faster, and they won\u0027t deadlock each other.\nThe threshold is raised high enough for them, so that there can be\nsufficient parallel progress of !GFP_IOFS reclaims.\n\n[akpm@linux-foundation.org: tweak comment]\nSigned-off-by: Wu Fengguang

sysfs entry\n\nSasha Levin recently reported a lockdep problem resulting from the new\nattribute propagation introduced by kmemcg series. In short, slab_mutex\nwill be called from within the sysfs attribute store function. This will\ncreate a dependency, that will later be held backwards when a cache is\ndestroyed - since destruction occurs with the slab_mutex held, and then\ncalls in to the sysfs directory removal function.\n\nIn this patch, I propose to adopt a strategy close to what\n__kmem_cache_create does before calling sysfs_slab_add, and release the\nlock before the call to sysfs_slab_remove. This is pretty much the last\noperation in the kmem_cache_shutdown() path, so we could do better by\nsplitting this and moving this call alone to later on. This will fit\nnicely when sysfs handling is consistent between all caches, but will look\nweird now.\n\nLockdep info:\n\n \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n [ INFO: possible circular locking dependency detected ]\n 3.7.0-rc4-next-20121106-sasha-00008-g353b62f #117 Tainted: G W\n -------------------------------------------------------\n trinity-child13/6961 is trying to acquire lock:\n (s_active#43){++++.+}, at: sysfs_addrm_finish+0x31/0x60\n\n but task is already holding lock:\n (slab_mutex){+.+.+.}, at: kmem_cache_destroy+0x22/0xe0\n\n which lock already depends on the new lock.\n\n the existing dependency chain (in reverse order) is:\n -\u003e #1 (slab_mutex){+.+.+.}:\n lock_acquire+0x1aa/0x240\n __mutex_lock_common+0x59/0x5a0\n mutex_lock_nested+0x3f/0x50\n slab_attr_store+0xde/0x110\n sysfs_write_file+0xfa/0x150\n vfs_write+0xb0/0x180\n sys_pwrite64+0x60/0xb0\n tracesys+0xe1/0xe6\n -\u003e #0 (s_active#43){++++.+}:\n __lock_acquire+0x14df/0x1ca0\n lock_acquire+0x1aa/0x240\n sysfs_deactivate+0x122/0x1a0\n sysfs_addrm_finish+0x31/0x60\n sysfs_remove_dir+0x89/0xd0\n kobject_del+0x16/0x40\n __kmem_cache_shutdown+0x40/0x60\n kmem_cache_destroy+0x40/0xe0\n mon_text_release+0x78/0xe0\n __fput+0x122/0x2d0\n ____fput+0x9/0x10\n task_work_run+0xbe/0x100\n do_exit+0x432/0xbd0\n do_group_exit+0x84/0xd0\n get_signal_to_deliver+0x81d/0x930\n do_signal+0x3a/0x950\n do_notify_resume+0x3e/0x90\n int_signal+0x12/0x17\n\n other info that might help us debug this:\n\n Possible unsafe locking scenario:\n\n CPU0 CPU1\n ---- ----\n lock(slab_mutex);\n lock(s_active#43);\n lock(slab_mutex);\n lock(s_active#43);\n\n *** DEADLOCK ***\n\n 2 locks held by trinity-child13/6961:\n #0: (mon_lock){+.+.+.}, at: mon_text_release+0x25/0xe0\n #1: (slab_mutex){+.+.+.}, at: kmem_cache_destroy+0x22/0xe0\n\n stack backtrace:\n Pid: 6961, comm: trinity-child13 Tainted: G W 3.7.0-rc4-next-20121106-sasha-00008-g353b62f #117\n Call Trace:\n print_circular_bug+0x1fb/0x20c\n __lock_acquire+0x14df/0x1ca0\n lock_acquire+0x1aa/0x240\n sysfs_deactivate+0x122/0x1a0\n sysfs_addrm_finish+0x31/0x60\n sysfs_remove_dir+0x89/0xd0\n kobject_del+0x16/0x40\n __kmem_cache_shutdown+0x40/0x60\n kmem_cache_destroy+0x40/0xe0\n mon_text_release+0x78/0xe0\n __fput+0x122/0x2d0\n ____fput+0x9/0x10\n task_work_run+0xbe/0x100\n do_exit+0x432/0xbd0\n do_group_exit+0x84/0xd0\n get_signal_to_deliver+0x81d/0x930\n do_signal+0x3a/0x950\n do_notify_resume+0x3e/0x90\n int_signal+0x12/0x17\n\nSigned-off-by: Glauber Costa \u003cglommer@parallels.com\u003e\nReported-by: Sasha Levin \u003csasha.levin@oracle.com\u003e\nCc: Michal Hocko \u003cmhocko@suse.cz\u003e\nCc: Kamezawa Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Pekka Enberg \u003cpenberg@kernel.org\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ebe945c27628fca03723582eba138acc2e2f3d15", "tree": "5998e8dd874aedf3b8873d0ffeaf658d10505655", "parents": [ "92e793495597af4135d94314113bf13eafb0e663" ], "author": { "name": "Glauber Costa", "email": "glommer@parallels.com", "time": "Tue Dec 18 14:23:10 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Dec 18 15:02:15 2012 -0800" }, "message": "memcg: add comments clarifying aspects of cache attribute propagation\n\nThis patch clarifies two aspects of cache attribute propagation.\n\nFirst, the expected context for the for_each_memcg_cache macro in\nmemcontrol.h.
