Do we need a comment here that explains where the numbers 65535 and 512 come from? > + u64 sector = blk_rq_pos(rq) >> (ilog2(sdp->sector_size) - 9); > + u32 nr_sectors = blk_rq_sectors(rq) >> (ilog2(sdp->sector_size) - 9); Please consider using logical_to_sectors() instead of open-coding this function. Thanks, Bart.
