   sync_min

   sync_max

     The two values, given as numbers of sectors, indicate a range

     withing the array where 'check'/'repair' will operate. Must be

     a multiple of chunk_size. When it reaches "sync_max" it will

     pause, rather than complete.

     You can use 'select' or 'poll' on "sync_completed" to wait for

     that number to reach sync_max.  Then you can either increase

     "sync_max", or can write 'idle' to "sync_action".
