Many thanks, I will look into this. I don't understand why SCSI
RESERVE/RELEASE can't be used as the locking mechanism though. Call me
stupid, but I'm only a student.
As an aside, can you (or anyone) see even the *vaguest* possible use for
my project? It basically allows you to construct a "virtual" switching
fabric with an arbitrary topology, attach a few fake disks to it, then
load an LLD on various hosts and they all see all the fake disks.
