Btrfs: check for an extent_op on the locked ref We could have possibly added an extent_op to the locked_ref while we dropped locked_ref->lock, so check for this case as well and loop around. Otherwise we could lose flag updates which would lead to extent tree corruption. Thanks, cc: stable@vger.kernel.org Signed-off-by: Josef Bacik <jbacik@fb.com> Signed-off-by: Chris Mason <clm@fb.com>
