  "message": "memcg: fix calculation of active_ratio\n\nCurrently, inactive_ratio of memcg is calculated at setting limit.\nbecause page_alloc.c does so and current implementation is straightforward\nporting.\n\nHowever, memcg introduced hierarchy feature recently.  In hierarchy\nrestriction, memory limit is not only decided memory.limit_in_bytes of\ncurrent cgroup, but also parent limit and sibling memory usage.\n\nThen, The optimal inactive_ratio is changed frequently.  So, everytime\ncalculation is better.\n\nTested-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nAcked-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nSigned-off-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
