  "message": "mm: fix anon_vma_clone() error treatment\n\nAndrew Morton noticed that the error return from anon_vma_clone() was\nbeing dropped and replaced with -ENOMEM (which is not itself a bug\nbecause the only error return value from anon_vma_clone() is -ENOMEM).\n\nI did an audit of callers of anon_vma_clone() and discovered an actual\nbug where the error return was being lost.  In __split_vma(), between\nLinux 3.11 and 3.12 the code was changed so the err variable is used\nbefore the call to anon_vma_clone() and the default initial value of\n-ENOMEM is overwritten.  So a failure of anon_vma_clone() will return\nsuccess since err at this point is now zero.\n\nBelow is a patch which fixes this bug and also propagates the error\nreturn value from anon_vma_clone() in all cases.\n\nFixes: ef0855d334e1 (\"mm: mempolicy: turn vma_set_policy() into vma_dup_policy()\")\nSigned-off-by: Daniel Forrest \u003cdan.forrest@ssec.wisc.edu\u003e\nReviewed-by: Michal Hocko \u003cmhocko@suse.cz\u003e\nCc: Konstantin Khlebnikov \u003ckoct9i@gmail.com\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Tim Hartrick \u003ctim@edgecast.com\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nCc: Michel Lespinasse \u003cwalken@google.com\u003e\nCc: Vlastimil Babka \u003cvbabka@suse.cz\u003e\nCc: \u003cstable@vger.kernel.org\u003e\t[3.12+]\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
