  HAMMER: Mass storage flush command support
  
  Add mass storage flush command support to HAMMER.  The HAMMER flush cycle
  issues async I/O in parallel and waits for it to complete before moving
  onto the next stage.  This occurs in two places.  The new flush command
  is issued after the async I/O, and then we wait on everything.
  
  Due to HAMMER's ability to gang writes asynchronously between stages the
  addition of the flush should not significantly impact performance.
