Subject: btrfs: handle btrfs_record_root_in_trans failure in btrfs_rename
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b0fec6fd330fe10cb68c137f6b7a17898ee69671;p=linux.git

btrfs: handle btrfs_record_root_in_trans failure in btrfs_rename

btrfs_record_root_in_trans will return errors in the future, so handle
the error properly in btrfs_rename.
