[PATCH 0/6] tcm_vhost/virtio-scsi WIP code for-3.6

["Nicholas A. Bellinger" <nab@linux-iscsi.org>]

From: Nicholas Bellinger <nab@linux-iscsi.org>

Hi folks,

This series contains patches required to update tcm_vhost <-> virtio-scsi
connected hosts <-> guests to run on v3.5-rc2 mainline code.  This series is
available on top of target-pending/auto-next here:

   git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git tcm_vhost

This includes the necessary vhost changes from Stefan to to get tcm_vhost
functioning, along a virtio-scsi LUN scanning change to address a client bug
with tcm_vhost I ran into..  Also, tcm_vhost driver has been merged into a single
source + header file that is now living under /drivers/vhost/, along with latest
tcm_vhost changes from Zhi's tcm_vhost tree.

Here are a couple of screenshots of the code in action using raw IBLOCK
backends provided by FusionIO ioDrive Duo:

   http://linux-iscsi.org/images/Virtio-scsi-tcm-vhost-3.5-rc2-4.png

So the next steps on my end will be converting tcm_vhost to submit backend I/O from
cmwq context, along with fio benchmark numbers between tcm_vhost/virtio-scsi and
virtio-scsi-raw using raw IBLOCK iomemory_vsl flash.

Please have a look vhost + virtio-scsi folks (mst + paolo CC'ed) and let us
know if you have any concerns.

Thanks!
