Well it is exactly what the patch does. We no longer do the "divide it by 8" thing each time we want to know the now defined TRIM_RANGE_NUM.
ata_set_lba_range_entries() has only been used by ata_scsi_write_same_xlat() (http://lxr.free-electrons.com/ident?i=ata_set_lba_range_entries, although the comment of it seems to tell otherwise). That's why I (could) changed the function itself and the param ("512") ata_scsi_write_same_xlat() passes to it.
