Subject: Re: [PATCH v2 13/15] KVM: x86/tdp_mmu: Make mmu notifier callbacks to
 check kvm_process

Subject: propagate enum kvm_process to MMU notifier callbacks

But again, the naming... I don't like kvm_process - in an OS process
is a word with a clear meaning. Yes, that is a noun and this is a
verb, but then naming an enum with a verb is also awkward.

Perhaps kvm_gfn_range_filter and range->attr_filter? A bit wordy but very clear:

enum kvm_tdp_mmu_root_types types =
    kvm_gfn_range_filter_to_root_types(kvm, range->attr_filter)

I think I like it.

This patch also should be earlier in the series; please move it after
patch 9, i.e. right after kvm_process_to_root_types is introduced.
