  "message": "net: don\u0027t use in_atomic() in gfp_any()\n\nThe problem is that in_atomic() will return false inside spinlocks if\nCONFIG_PREEMPT\u003dn.  This will lead to deadlockable GFP_KERNEL allocations\nfrom spinlocked regions.\n\nSecondly, if CONFIG_PREEMPT\u003dy, this bug solves itself because networking\nwill instead use GFP_ATOMIC from this callsite.  Hence we won\u0027t get the\nmight_sleep() debugging warnings which would have informed us of the buggy\ncallsites.\n\nSolve both these problems by switching to in_interrupt().  Now, if someone\nruns a gfp_any() allocation from inside spinlock we will get the warning\nif CONFIG_PREEMPT\u003dy.\n\nI reviewed all callsites and most of them were too complex for my little\nbrain and none of them documented their interface requirements.  I have no\nidea what this patch will do.\n\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: David S. Miller \u003cdavem@davemloft.net\u003e\n",
