this series attempts to modularize the CDB parsing, cleaning it up
and allow for non-SBC virtual backends. It also helps to push a lot
of passthrough specific code into the pscsi backend.
While I can verify the virtual SBC mode works just fine with it, I have
so far failed to actually get pscsi running using lio-tool.
I tried variants of this command line:
tcm_node --scsi pscsi_0/foo scsi0 0:0:0:0
and always get errors. For the specific one above it looks like:
sh: line 0: echo: write error: Invalid argument
pSCSI: createvirtdev failed for enable_opt with scsi_channel_id=scsi0
