    block: remove artifical max_hw_sectors cap · 34b48db6
    Christoph Hellwig authored
    Set max_sectors to the value the drivers provides as hardware limit by
    default.  Linux had proper I/O throttling for a long time and doesn't
    rely on a artifically small maximum I/O size anymore.  By not limiting
    the I/O size by default we remove an annoying tuning step required for
    most Linux installation.
    
    Note that both the user, and if absolutely required the driver can still
    impose a limit for FS requests below max_hw_sectors_kb.
