I think you're missing a lot of MMU notifier work by calling this directly. It probably works in every scenario you've tested, but won't work for others. I see you're using VM_MIXEDMAP -- would it make sense to use VM_PFNMAP instead and use zap_vma_ptes()? Or would it make sense to change zap_vma_ptes() to handle VM_MIXEDMAP as well as VM_PFNMAP? _______________________________________________ Virtualization mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/virtualization
