[Qemu-devel] [PATCH v4 0/6] Rework vhost memory region updates

[Dr. David Alan Gilbert (git)]

From: "Dr. David Alan Gilbert" <address@hidden>

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.
 
v4
  Rework based on comments from Paolo; now using add/nop rather
  than doing another flatview walk.
 
Dave
