    libata: add extra internal command · 28361c40
    Jens Axboe authored
    Bump the internal tag to 32, instead of stealing the last tag in
    our regular command space. This works just fine, since we don't
    actually need a separate hardware tag for this. Internal commands
    cannot coexist with NCQ commands.
    
    As a bonus, we get rid of the special casing of what tag to use
    for the internal command.
    
    This is in preparation for utilizing all 32 commands for normal IO.
