BLK_QUEUE_ALIGNMENT_(9)                   Block Devices                   BLK_QUEUE_ALIGNMENT_(9)



NAME
       blk_queue_alignment_offset - set physical block alignment offset

SYNOPSIS
       void blk_queue_alignment_offset(struct request_queue * q, unsigned int offset);

ARGUMENTS
       q
           the request queue for the device

       offset
           alignment offset in bytes

DESCRIPTION
       Some devices are naturally misaligned to compensate for things like the legacy DOS
       partition table 63-sector offset. Low-level drivers should call this function for devices
       whose first sector is not naturally aligned.
