On a side note, I noticed that ll_rw_blk does not appear to check for
these devices, which would seem to indicate that if you attempt to do
I/O to some of them, the request will fall on the floor since
ll_rw_blk.c only checks for certain ranges of devices. Is it also
assumed that these folks have some way they use to r/w these devices.
