This is a part of the several patches to reduce mem cgroup\noverhead. I had posted other approaches earlier (including using percpu\ncounters). Those patches will be a natural addition and will be added\niteratively on top of these.\n\nThe patch stops resource counter accounting for the root cgroup. The data\nfor display is derived from the statisitcs we maintain via\nmem_cgroup_charge_statistics (which is more scalable). What happens today\nis that, we do double accounting, once using res_counter_charge() and once\nusing memory_cgroup_charge_statistics(). For the root, since we don\u0027t\nimplement limits any more, we don\u0027t need to track every charge via\nres_counter_charge() and check for limit being exceeded and reclaim.\n\nThe main mem-\u003eres usage_in_bytes can be derived by summing the cache and\nrss usage data from memory statistics (MEM_CGROUP_STAT_RSS and\nMEM_CGROUP_STAT_CACHE). However, for memsw-\u003eres usage_in_bytes, we need\nadditional data about swapped out memory. This patch adds a\nMEM_CGROUP_STAT_SWAPOUT and uses that along with MEM_CGROUP_STAT_RSS and\nMEM_CGROUP_STAT_CACHE to derive the memsw data.

The overall goal is to\n\n1. Add a memory cgroup to the RB-Tree when the soft limit is exceeded.\n We are careful about updates, updates take place only after a particular\n time interval has passed\n2. We remove the node from the RB-Tree when the usage goes below the soft\n limit\n\nThe next set of patches will exploit the RB-Tree to get the group that is\nover its soft limit by the largest amount and reclaim from it, when we\nface memory contention.\n\n[hugh.dickins@tiscali.co.uk: CONFIG_CGROUP_MEM_RES_CTLR\u003dy CONFIG_PREEMPT\u003dy fails to boot]\nSigned-off-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nCc: Jiri Slaby \u003cjirislaby@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": "296c81d89f4f14269f7346f81442910158c0a83a", "tree": "cf0e1facd1fed8282c1885bc4126e7bca1928712", "parents": [ "a6df63615b943dbef22df04c19f4506330fe835e" ], "author": { "name": "Balbir Singh", "email": "balbir@linux.vnet.ibm.com", "time": "Wed Sep 23 15:56:36 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Sep 24 07:20:59 2009 -0700" }, "message": "memory controller: soft limit interface\n\nAdd an interface to allow get/set of soft limits.
