  "message": "memcg: fix Bad page state after replace_page_cache\n\nMy 9ce70c0240d0 \"memcg: fix deadlock by inverting lrucare nesting\" put a\nnasty little bug into v3.3\u0027s version of mem_cgroup_replace_page_cache(),\nsometimes used for FUSE.  Replacing __mem_cgroup_commit_charge_lrucare()\nby __mem_cgroup_commit_charge(), I used the \"pc\" pointer set up earlier:\nbut it\u0027s for oldpage, and needs now to be for newpage.  Once oldpage was\nfreed, its PageCgroupUsed bit (cleared above but set again here) caused\n\"Bad page state\" messages - and perhaps worse, being missed from newpage.\n(I didn\u0027t find this by using FUSE, but in reusing the function for tmpfs.)\n\nSigned-off-by: Hugh Dickins \u003chughd@google.com\u003e\nCc: stable@vger.kernel.org [v3.3 only]\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
