Btrfs: avoid unnecessary utimes update in incremental send
When we're finishing processing of an inode, if we're dealing with a directory inode that has a pending move/rename operation, we don't need to send a utimes update instruction to the send stream, as we'll do it later after doing the move/rename operation. Therefore we save some time here building paths and doing btree lookups. Signed-off-by: Filipe David Borba Manana <fdmanana@gmail.com> Signed-off-by: Josef Bacik <jbacik@fb.com>
