In this case, swap-out will\nbe done only by global-LRU.\n\nBut, under current implementation, memory.limit_in_bytes is checked at\nfirst and try_to_free_page() may do swap-out. But, that swap-out is\nuseless for memsw.limit_in_bytes and the thread may hit limit again.\n\nThis patch tries to fix the current behavior at memory.limit \u003d\u003d\nmemsw.limit case. And documentation is updated to explain the behavior of\nthis special case.\n\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Daisuke Nishimura \u003cnishimura@mxp.nes.nec.co.jp\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Dhaval Giani \u003cdhaval@linux.vnet.ibm.com\u003e\nCc: YAMAMOTO Takashi \u003cyamamoto@valinux.co.jp\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "8a9478ca7f4bcb8945cec7f95d52dae2d5e50cbd", "tree": "935e6ee3340ebe999374b54967cc2fa14e8d0060", "parents": [ "20ebcdda78a282d1d5266887ddf8a2d670182576" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Wed Jun 17 16:27:17 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jun 18 13:03:47 2009 -0700" }, "message": "memcg: fix swap accounting\n\nThis patch fixes mis-accounting of swap usage in memcg.\n\nIn the current implementation, memcg\u0027s swap account is uncharged only when\nswap is completely freed.
