From: David Sterba Date: Tue, 12 Dec 2017 20:43:52 +0000 (+0100) Subject: btrfs: sink unlock_extent parameter gfp_flags X-Git-Tag: v4.16-rc1~180^2~46 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=e43bbe5e16d87b40f3b382b3a43b0142d6d1193d;p=uclinux-h8%2Flinux.git btrfs: sink unlock_extent parameter gfp_flags All callers pass either GFP_NOFS or GFP_KERNEL now, so we can sink the parameter to the function, though we lose some of the slightly better semantics of GFP_KERNEL in some places, it's worth cleaning up the callchains.
