    [PATCH] md: improve the interface to sync_request · 57afd89f
    NeilBrown authored
    1/ change the return value (which is number-of-sectors synced)
     from 'int' to 'sector_t'.
     The number of sectors is usually easily small enough to fit
     in an int, but if resync needs to abort, it may want to return
     the total number of remaining sectors, which could be large.
     Also errors cannot be returned as negative numbers now, so use
     0 instead
    2/ Add a 'skipped' return parameter to allow the array to report
     that it skipped the sectors.  This allows md to take this into account
     in the speed calculations.
     Currently there is no important skipping, but the bitmap-based-resync
     that is coming will use this.
