Subject: Btrfs: take ordered root lock when removing ordered operations inode
From: Josef Bacik <[email protected]>
commit 93858769172c4e3678917810e9d5de360eb991cc upstream.
A user reported a list corruption warning from btrfs_remove_ordered_extent, it
is because we aren't taking the ordered_root_lock when we remove the inode from
the ordered operations list. Thanks,
