Subject: mm/vmscan: remove redundant __GFP_NOWARN
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bd63d0fde2a2c328fe30456b8aa2521222c6f3fe;p=thirdparty%2Fkernel%2Flinux.git

mm/vmscan: remove redundant __GFP_NOWARN

The __GFP_NOWARN flag was included in GFP_NOWAIT since commit 16f5dfbc851b
("gfp: include __GFP_NOWARN in GFP_NOWAIT").  So remove the redundant
__GFP_NOWARN flag.
