NAME

       blk_queue_hardsect_size - set hardware sector size for the queue

SYNOPSIS

       void blk_queue_hardsect_size  (request_queue_t * q,
                                       unsigned short size);

ARGUMENTS

       q      the request queue for the device

       size   the hardware sector size, in bytes

DESCRIPTION

       This should typically be set to the lowest possible  sector  size  that
       the  hardware  can  operate  on  (possible  without  reverting  to even
       internal read-modify-write operations).  Usually  the  default  of  512
       covers most hardware.
