 No.  That change untangled sync from suspendctl.  Before a file system
 would sync before suspending, now we suspend and sync where needed.
 It could be sufficient to call ffs_sync(WAIT) before going from
 non-log to log.  The update now runs on a suspended file system so
 after sync no new dirty buffers appear.
