Subdirectories will be available in the next patch. The above layout
or something similar seems OK. In case you've missed it, I've finally
decided on the naming for SCSI discs: /dev/sd/c0b0t0u0s0
controller(host),bus(channel),target(id),unit(lun),stripe(partition).
Any further arguments on that topic may be forwarded to Linus ;-)
