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

ARGUMENTS

q

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.
