  "message": "memcg: fix memory migration of shmem swapcache\n\nIn the current implementation mem_cgroup_end_migration() decides whether\nthe page migration has succeeded or not by checking \"oldpage-\u003emapping\".\n\nBut if we are tring to migrate a shmem swapcache, the page-\u003emapping of it\nis NULL from the begining, so the check would be invalid.  As a result,\nmem_cgroup_end_migration() assumes the migration has succeeded even if\nit\u0027s not, so \"newpage\" would be freed while it\u0027s not uncharged.\n\nThis patch fixes it by passing mem_cgroup_end_migration() the result of\nthe page migration.\n\nSigned-off-by: Daisuke Nishimura \u003cnishimura@mxp.nes.nec.co.jp\u003e\nReviewed-by: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nAcked-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nAcked-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nCc: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nReviewed-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
