[PULL net-next] vhost-net fixes for 3.1

[PULL net-next] vhost-net fixes for 3.1

[Michael S. Tsirkin]

Here's Jason's fix for a theoretical event loss
on migration (tweaked by me to update the test
module as well), and a refcounting fix by me
for a bug in the new zerocopy mode.

I thought hard about merging Jason's patches for 3.0
as well, but in the end I think it's not worth
the risk of breaking something at this stage.

Please pull for 3.1, thanks a lot!

The following changes since commit 81fc70d86527a1450560709500ca5f52e661da1f:

  net: can: remove custom hex_to_bin() (2011-07-18 11:31:43 -0700)

are available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git vhost-net-next

Jason Wang (2):
      vhost: init used ring after backend was set
      vhost: set log when updating used flags or avail event

Michael S. Tsirkin (1):
      vhost: fix zcopy reference counting

You got the new one actually, so nothing needs to be done,
I think.

Thanks!
