Subject: btrfs: move transaction abort to the error site in btrfs_delete_free_space_tree()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0896ce7550399a32a77a25a21eeb8daaae398f7f;p=linux.git

btrfs: move transaction abort to the error site in btrfs_delete_free_space_tree()

The recommended pattern for transaction abort after error is to place it
right after the error is handled. That way it's easier to locate where
it failed and help debugging.
