From: Peng Hao <[email protected]>

No 'kvmp_mmu_pages', it should be 'kvm_mmu_page'. And
struct kvm_mmu_pages and struct kvm_mmu_page are different structures,
here should be kvm_mmu_page.
kvm_mmu_pages is defined in arch/x86/kvm/mmu/mmu.c.

I agree that "struct <name>s" is a bad/misleading way to make a struct
plural in comments. The way I prefer to do it is "<name> structs".
That avoids changing the <name> and still makes it clear it's plural.
So in this case the comment would be:

/*
* List of kvm_mmu_page structs being used as roots.
* All kvm_mmu_page structs in the list should have
* tdp_mmu_page set.
*/

> + * All struct kvm_mmu_page in the list should have

+1, I like that approach. FWIW, "struct kvm_mmu_pages" will likely be renamed in
the not-too-distant future[*], but I think it's still worth changing this to follow
David's suggestion.
