Subject: [PATCH] The mdcheck script now adds messages to the system log
to
 report on progress of the array check.  These are issued when mdcheck
starts
 or continues a check and when it suspends a check at the expiration of
 duration.  The messages either report the check has completed or the
block
 number of the current and last block in the array and the percentage of
 completion.
