gfs2: allow journal replay to hold sd_log_flush_lock
Before this patch, journal replays could stomp on log flushes and each other because both log flushes and journal replays used the same sd_log_bio. Function gfs2_log_flush prevents other log flushes from interfering by taking the sd_log_flush_lock rwsem during the flush. However, it does not protect against journal replays. This patch allows the journal replay to take the same sd_log_flush_lock rwsem so use of the sd_log_bio is not stomped. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
