Hi folks,

[I am resending to fix the broken thread in the previous one.]

This patchset adds vhost-blk support. vhost-blk is a in kernel virito-blk
device accelerator. Compared to userspace virtio-blk implementation, vhost-blk
gives about 5% to 15% performance improvement.

Same thing as tcm_host comment:

	It seems not 100% clear whether this driver will have major
	userspace using it. And if not, it would be very hard to support a
	driver when recent userspace does not use it in the end.

	I think a good idea for 3.6 would be to make it depend on
	CONFIG_STAGING.  Then we don't commit to an ABI.  For this, you can add
	a separate Kconfig and source it from drivers/staging/Kconfig.  Maybe it
	needs to be in a separate directory drivers/vhost/staging/Kconfig.

I Cc'd the list of tcm_host in the hope that you can cooperate on this.
