  "message": "mm: memcg: use proper memcg in limit bypass\n\nCommit 84235de394d9 (\"fs: buffer: move allocation failure loop into the\nallocator\") allowed __GFP_NOFAIL allocations to bypass the limit if they\nfail to reclaim enough memory for the charge.  But because the main test\ncase was on a 3.2-based system, the patch missed the fact that on newer\nkernels the charge function needs to return root_mem_cgroup when\nbypassing the limit, and not NULL.  This will corrupt whatever memory is\nat NULL + percpu pointer offset.  Fix this quickly before problems are\nreported.\n\nSigned-off-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nAcked-by: Michal Hocko \u003cmhocko@suse.cz\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
