The patch titled
Subject: mm,oom: do not loop !__GFP_FS allocation if the OOM killer is disabled
has been removed from the -mm tree. Its filename was
mmoom-do-not-loop-__gfp_fs-allocation-if-the-oom-killer-is-disabled.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Tetsuo Handa <penguin-kernel@xxxxxxxxxxxxxxxxxxx>
Subject: mm,oom: do not loop !__GFP_FS allocation if the OOM killer is disabled
After the OOM killer is disabled during suspend operation, any
!__GFP_NOFAIL && __GFP_FS allocations are forced to fail. Thus, any
!__GFP_NOFAIL && !__GFP_FS allocations should be forced to fail as well.
