[Qemu-devel] [PATCH 0/6] Migration: Small fixes and improvements

["Dr. David Alan Gilbert (git)" <dgilbert@redhat.com>]

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>

This is a set of 4 small fixes and improvements I've been collecting
during the 2.5 freeze; I've added in a couple of Zhanghailiang's patches
that are easier to merge before rather than after.
(Of which one I've added a small fix of my own, see the message)

Jiri was after events from the incoming postcopy side to make it
easy for libvirt; I'd forgotten to add them - Zhanghailiang's
patches change the way the events get sent on the incoming side.

Jiri also wanted an event on the outgoing side at each pass,
which makes it easy for libvirt to trigger the transition to postcopy.

The other two patches avoid a couple of buffer copies on the incoming
side; although in both xbzrle and multithread compression it's rare that
the destination is the slow path (but one patch is trivial and the
other saves code).
