Well it's mainly to "pre-de-couple" BLK_DEF_MAX_SECTORS from ATA
drives. If we left the field unset, the scsi disk driver will fall
back to BLK_DEF_MAX_SECTORS when setting the block limit "max_sectors"
(while its cap "max_hw_sectors" is set by libata depending on whether
the drive supports LBA48 o

an optimal xfer size"), the scsi disk driver (correctly) derive both
of the queue limits "io_opt" and "max_sectors" from the optimal
transfer length field.
In case we would like the two limits to be derived from a v
