Subject: [PATCH v2 0/3] add track_remove_slot and remove track_flush_slot

This series is based on Sean's series
https://lore.kernel.org/all/20221110014821.1548347-1-seanjc@google.com/,
which allows KVM internal user of page track not to rely on the page track
hook .track_flush_slot.

Page track hook track_flush_slot is for notification of slot flush and
is called when a slot DELETE/MOVE is on-going.

Page track hook track_remove_slot is for notification of slot removal
and is called when the slot DELETE/MOVE has been committed.

As KVMGT, the only external user of page track, actually only cares about
when slot removal indeed happens, this series switches KVMGT to use the new
hook .track_remove_slot.
And as there are no users to .track_flush_slot any more, this hook is
removed.

v2:
Corrected wrong email address of Sean. sorry.

Yan Zhao (3):
  KVM: x86: add a new page track hook track_remove_slot
  drm/i915/gvt: switch from track_flush_slot to track_remove_slot
  KVM: x86: Remove the unused page track hook track_flush_slot
