btrfs: update barrier in should_cow_block Once there was a simple int force_cow that was used with the plain barriers, and then converted to a bit, so we should use the appropriate barrier helper. Other variables in the complex if condition do not depend on a barrier, so we should be fine in case the atomic barrier becomes a no-op. Signed-off-by: David Sterba <dsterba@suse.com>
