Fengguang Wu reminded me that there were outstanding sparse reports in the ceph and rbd code. This patch fixes these problems in rbd that lead to those reports: - Convert functions that are never referenced externally to have static scope. - Add a lockdep annotation to rbd_request_fn(), because it releases a lock before acquiring it again.
