NAME
       blk_limits_io_min - set minimum request size for a device

SYNOPSIS
       void blk_limits_io_min(struct queue_limits * limits, unsigned int min);

ARGUMENTS
       limits
           the queue limits

       min
           smallest I/O size in bytes

       This function can be used to signal the smallest I/O the device can perform without
       incurring a performance penalty.
