The READ/WRITE LONG commands are theoretically obsolete,
but the majority of drives in existance still implement them.

The WRITE_LONG and WRITE_LONG_ONCE commands are of particular
interest for fault injection testing -- eg. creating "media errors"
at specific locations on a disk.

The fussy bit is that these commands require a non-standard
sector size, usually 520 bytes instead of 512.
..

A possible nice side-benefit, is that this patch also prepares libata
for future extension to use drives with a mix of physical sector sizes.

More work required for that, of course, but not *much* more.

Cheers
