[PATCH v2 0/1] KVM: s390: fix a newly introduced bug

Posted by Claudio Imbrenda 9 months, 3 weeks ago

Fix race when making a page secure (hold pte lock again)

This should fix the issues I have seen, which I think/hope are also the same
issues that David found.


v1->v2:
* major refactoring
* walk the page tables only once
* when importing, manually fault in pages if needed
