[Qemu-devel] [PATCH v5 0/7] Rework vhost memory region updates

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

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

Hi,
  This patch set reworks the way the vhost code handles changes in
physical address space layout that came from a discussion with Igor.

Its intention is to simplify a lot of the update code,
and to make it easier for the postcopy+shared code to
do the hugepage alignments that are needed.

Instead of inserting/removing each section during the add/del
callbacks of the listener, we start afresh and build a list
from the add and nop callbacks, then at the end compare the list
we've built with the exisiting list.

v5
  Solve the unref race found by Igor with a new 1st patch
  Now we've got a temporary section list rework the rest of the set
   around that.

Dr. David Alan Gilbert (7):
  vhost: Build temporary section list and deref after commit
  vhost: Move log_dirty check
  vhost: Simplify ring verification checks
  vhost: Merge sections added to temporary list
  vhost: Regenerate region list from changed sections list
  vhost: Clean out old vhost_set_memory and friends
  vhost: Merge and delete unused callbacks
