X-Git-Tag: v6.6.7~2168^2~63
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0d394cca8435045f909bd2bb099575b11452e19a;p=platform%2Fkernel%2Flinux-starfive.git

btrfs: use btrfs_finish_ordered_extent to complete buffered writes

Use the btrfs_finish_ordered_extent helper to complete compressed writes
using the bbio->ordered pointer instead of requiring an rbtree lookup
in the otherwise equivalent btrfs_mark_ordered_io_finished called from
btrfs_writepage_endio_finish_ordered.
