Subject: btrfs: readdir: use GFP_KERNEL
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=49e350a4919fb1751127111cf6dd6fed02815781;p=openwrt%2Fstaging%2Fblogic.git

btrfs: readdir: use GFP_KERNEL

Readdir is initiated from userspace and is not on the critical
writeback path, we don't need to use GFP_NOFS for allocations.
