[RFC-v5] tcm_vhost: Initial merge for vhost level target fabric driver
From: Nicholas Bellinger <nab at linux-iscsi.org>
Hello KVM + QEMU folks,
This is -v5 of the in-flight tcm_vhost fabric driver for KVM host virtualized
target support using the in-kernel storage stack with for-3.6 code.
The changes since -v4 have been pretty minimal. A new GET_ABI_VERSION ioctl
has been added as requested by Anthony & Co, and after some back <-> forth on

[PATCH] tcm_vhost: Add hotplug/hotunplug support
In commit 365a7150094 ([SCSI] virtio-scsi: hotplug support for
virtio-scsi), hotplug support is added to virtio-scsi.
This patch adds hotplug and hotunplug support to tcm_vhost.
You can create or delate a LUN in targetcli to hotplug or hotplug a LUN
in guest.

[PATCH 3/8] vhost scsi: alloc cmds per vq instead of session

[PATCH 3/5] vhost-scsi: Remove vhost_scsi_mutex from port link/unlink
We don't need the vhost_scsi_mutex in vhost_scsi_port_link and
vhost_scsi_port_unlink because LIO has a refcount on the se_tpg for us,
so it can't be removed while these functions are called. This removes the
vhost_scsi_mutex from those functions to avoid cases where we are adding
or removing LUNs to vhost-deviceA but are stuck waiting on the
vhost_scsi_mutex because we are running

[PATCH v3] tcm_vhost: Multi-target support
In order to take advantages of Paolo's multi-queue virito-scsi, we need
multi-target support in tcm_vhost first. Otherwise all the requests go
to one queue and other queues are idle.
This patch makes:
1. All the targets under the wwpn is seen and can be used by guest.
2. No need to pass the tpgt number in struct vhost_scsi_target to
tcm_vhost.ko. Only wwpn is needed.
3. We can always pass
