It should be a SCSI upper-level driver like sd.c, sr.c, st.c and osst.c.
It may make most sense for it to be implemented as a part of sd.c,
or it might be better to do it by implementing a new raid_sd.c.

Start with 2.6.16-rc5 (the most recent release by Linus).  It shouldn't
be much effort to forward-port it whern it comes to merge it.
