If anyone has any objections, please let me know. ------------------ From: Johannes Thumshirn [ Upstream commit 3c44cd3c79fcb38a86836dea6ff8fec322a9e68c ] Now that btrfs_zone_finish_endio_workfn() is directly calling do_zone_finish() the only caller of btrfs_zone_finish_endio() is btrfs_finish_one_ordered(). btrfs_finish_one_ordered() already has error handling in-place so btrfs_zone_finish_endio() can return an error if the block group lookup fails. Also as btrfs_zone_finish_endio() already checks for zoned filesystems and returns early, there's no need to do this in the caller.
