So yeah, this code is still considered RFC at this point for-3.6, but
I'd like to get this into target-pending/for-next in next week for more
feedback and start collecting signoffs for the necessary pieces that

By that time the cmwq conversion of tcm_vhost should be in place as
well..

<nod>, I'll send patch #5 separately to linux-scsi -> James and CC
stable following Paolo's request.
