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.
Adding it to staging allows more people to try it out, so that's a
good thing. If I get a moment to play with it I'll let you know the
results.
