Subject: xenpaging: populate paged-out pages unconditionally
|
|
|
|
Populate a page unconditionally to avoid missing a page-in request.
|
|
If the page is already in the process of being paged-in, the this vcpu
|
|
will be stopped and later resumed once the page content is usable again.
|
|
|
|
This matches other p2m_mem_paging_populate usage in the source tree.
