  "message": "memcg: handle panic_on_oom\u003dalways case\n\nPresently, if panic_on_oom\u003d2, the whole system panics even if the oom\nhappend in some special situation (as cpuset, mempolicy....).  Then,\npanic_on_oom\u003d2 means painc_on_oom_always.\n\nNow, memcg doesn\u0027t check panic_on_oom flag. This patch adds a check.\n\nBTW, how it\u0027s useful ?\n\nkdump+panic_on_oom\u003d2 is the last tool to investigate what happens in\noom-ed system.  When a task is killed, the sysytem recovers and there will\nbe few hint to know what happnes.  In mission critical system, oom should\nnever happen.  Then, panic_on_oom\u003d2+kdump is useful to avoid next OOM by\nknowing precise information via snapshot.\n\nTODO:\n - For memcg, it\u0027s for isolate system\u0027s memory usage, oom-notiifer and\n   freeze_at_oom (or rest_at_oom) should be implemented. Then, management\n   daemon can do similar jobs (as kdump) or taking snapshot per cgroup.\n\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nReviewed-by: Daisuke Nishimura \u003cnishimura@mxp.nes.nec.co.jp\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
