Subject[ 26/34] vhost: fix mergeable bufs on BE hosts
Date
3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Michael S. Tsirkin" <mst@redhat.com>

commit 910a578f7e9400a78a3b13aba0b4d2df16a2cb05 upstream.

We copy head count to a 16 bit field, this works by chance on LE but on
BE guest gets 0. Fix it up.
