Technically it's the host OS on top..

Actually, that's what it's defined for for tape drives (SSC). For disk=20
(SBC) devices, it's Stop/Start Unit.

Sunchronise Cache is easy. There, ehm, is the fsync_range() system call=20
which, ehm, just so happens to have the needed semantics for this.

All of the above are optional. Synchronize Cache is easy, and PR-IN is=20
needed for a cluster. You'll get far w/o the other two.

You can hobble along w/o PR-IN & Out.

I think a more important issue to address is the following warnings:

Feb 24 15:15:16 barney genunix: [ID 587529 kern.warning] WARNING:
