[Qemu-devel] [PATCH v2 0/4] memory/vfio: notify region_del() when unregister listeners

[Peter Xu <peterx@redhat.com>]

v2
- add begin() hooks [Paolo]
- move vfio patch to front [Paolo]
- one more patch for arm devlistener unregister [Paolo]
- one more patch for vhost traces
- removing RFC tag

This series fixes bug reported here:

  https://bugzilla.redhat.com/show_bug.cgi?id=1531393

The first patch only adds traces for vhost, with which I tested on
vhost to make sure that my last patch works as expected with vhost.
Please pick it if anyone wants, or ignore it if no one likes it.

The 2nd patch is the arm fix for preparation of the last patch.

The 3rd patch is the vfio fix for preparation of the last patch.

The 4th patch is the core fix of the problem.

Please review, thanks.

Thanks.

Peter Xu (4):
  vhost: add traces for memory listeners
  arm: postpone device listener unregister
  vfio: listener unregister before unset container
  memory: do explicit cleanup when remove listeners
