One is for readdir, it\u0027s in this nice\nsequential order and works out brilliantly for readdir. However if you use ls,\nit usually stat\u0027s each file it gets from readdir. This is where the second\nindex comes in, which is based on a hash of the name of the file. So then the\nlookup has to lookup this index, and then lookup the inode. The index lookup is\ngoing to be in random order (since its based on the name hash), which gives us\nless than stellar performance. Since we know the inode location from the\nreaddir index, I create a dummy dentry and copy the location key into\ndentry-\u003ed_fsdata. Then on lookup if we have d_fsdata we use that location to\nlookup the inode, avoiding looking up the other directory index.

Targeted async\ndraining has been introduced by 26fe6168 (memcg: fix percpu cached\ncharge draining frequency) to reduce the cpu workers number.\n\nsync draining is currently triggered only from mem_cgroup_force_empty\nwhich is triggered only by userspace (mem_cgroup_force_empty_write) or\nwhen a cgroup is removed (mem_cgroup_pre_destroy). Although these are\nnot usually frequent operations it still makes some sense to do targeted\ndraining as well, especially if the box has many CPUs.\n\nThis patch unifies both methods to use the single code (drain_all_stock)\nwhich relies on the original async implementation and just adds\nflush_work to wait on all caches that are still under work for the sync\nmode.

While A releases the mutex and\ncalls mem_cgroup_out_of_memory others will wake up (one after another)\nand increase the counter and fall into sleep (memcg_oom_waitq).\n\nOnce A finishes mem_cgroup_out_of_memory it takes the mutex again and\ndecreases oom_lock and wakes other tasks (if releasing memory by\nsomebody else - e.g. killed process - hasn\u0027t done it yet).\n\nA testcase would look like:\n Assume malloc XXX is a program allocating XXX Megabytes of memory\n which touches all allocated pages in a tight loop\n # swapoff SWAP_DEVICE\n # cgcreate -g memory:A\n # cgset -r memory.oom_control\u003d0 A\n # cgset -r memory.limit_in_bytes\u003d 200M\n # for i in `seq 100`\n # do\n # cgexec -g memory:A malloc 10 \u0026\n # done\n\nThe main problem here is that all processes still race for the mutex and\nthere is no guarantee that we will get counter back to 0 for those that\ngot back to mem_cgroup_handle_oom. In the end the whole convoy\nin/decreases the counter but we do not get to 1 that would enable\nkilling so nothing useful can be done. The time is basically unbounded\nbecause it highly depends on scheduling and ordering on mutex (I have\nseen this taking hours...).\n\nThis patch replaces the counter by a simple {un}lock semantic. As\nmem_cgroup_oom_{un}lock works on the a subtree of a hierarchy we have to\nmake sure that nobody else races with us which is guaranteed by the\nmemcg_oom_mutex.\n\nWe have to be careful while locking subtrees because we can encounter a\nsubtree which is already locked: hierarchy:\n\n A\n / \\\n B \\\n /\\ \\\n C D E\n\nB - C - D tree might be already locked. While we want to enable locking\nE subtree because OOM situations cannot influence each other we\ndefinitely do not want to allow locking A.\n\nTherefore we have to refuse lock if any subtree is already locked and\nclear up the lock for all nodes that have been set up to the failure\npoint.\n\nOn the other hand we have to make sure that the rest of the world will\nrecognize that a group is under OOM even though it doesn\u0027t have a lock.\nTherefore we have to introduce under_oom variable which is incremented\nand decremented for the whole subtree when we enter resp. leave\nmem_cgroup_handle_oom. under_oom, unlike oom_lock, doesn\u0027t need be\nupdated under memcg_oom_mutex because its users only check a single\ngroup and they use atomic operations for that.\n\nThis can be checked easily by the following test case:\n\n # cgcreate -g memory:A\n # cgset -r memory.use_hierarchy\u003d1 A\n # cgset -r memory.oom_control\u003d1 A\n # cgset -r memory.limit_in_bytes\u003d 100M\n # cgset -r memory.memsw.limit_in_bytes\u003d 100M\n # cgcreate -g memory:A/B\n # cgset -r memory.oom_control\u003d1 A/B\n # cgset -r memory.limit_in_bytes\u003d20M\n # cgset -r memory.memsw.limit_in_bytes\u003d20M\n # cgexec -g memory:A/B malloc 30 \u0026 #-\u003ethis will be blocked by OOM of group B\n # cgexec -g memory:A malloc 80 \u0026 #-\u003ethis will be blocked by OOM of group A\n\nWhile B gets oom_lock A will not get it. Both of them go into sleep and\nwait for an external action. We can make the limit higher for A to\nenforce waking it up\n\n # cgset -r memory.memsw.limit_in_bytes\u003d300M A\n # cgset -r memory.limit_in_bytes\u003d300M A\n\nmalloc in A has to wake up even though it doesn\u0027t have oom_lock.\n\nFinally, the unlock path is very easy because we always unlock only the\nsubtree we have locked previously while we always decrement under_oom.\n\nSigned-off-by: Michal Hocko \u003cmhocko@suse.cz\u003e\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Balbir Singh \u003cbsingharora@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "bb2a0de92c891b8feeedc0178acb3ae009d899a8", "tree": "c2c0b3ad66c8da0e48c021927b2d747fb08b7ef3", "parents": [ "1f4c025b5a5520fd2571244196b1b01ad96d18f6" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Tue Jul 26 16:08:22 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jul 26 16:49:42 2011 -0700" }, "message": "memcg: consolidate memory cgroup lru stat functions\n\nIn mm/memcontrol.c, there are many lru stat functions as..\n\n mem_cgroup_zone_nr_lru_pages\n mem_cgroup_node_nr_file_lru_pages\n mem_cgroup_nr_file_lru_pages\n mem_cgroup_node_nr_anon_lru_pages\n mem_cgroup_nr_anon_lru_pages\n mem_cgroup_node_nr_unevictable_lru_pages\n mem_cgroup_nr_unevictable_lru_pages\n mem_cgroup_node_nr_lru_pages\n mem_cgroup_nr_lru_pages\n mem_cgroup_get_local_zonestat\n\nSome of them are under #ifdef MAX_NUMNODES \u003e1 and others are not.\nThis seems bad.
