blktap needs zap_page_range() exported
Last modified: 2007-11-30 17:07:38 EST
Description of problem:
The blktap backend needs zap_page_range() exported: it uses this to clear its
guest mappings during driver shutdown.
Current RHEL-5 has
as an implicit part of the PV-FB patch. But the new upstream PV-FB does not
have that, and blktap still needs it.
So updating the blktap patch will break PV-FB.
So we need to move that chunk from the PV-FB patch to the blktap-fixes patch in
order to preserve it.
Version-Release number of selected component (if applicable):
QE ack for RHEL5.
