Subject: Re: [PATCH v2 20/27] KVM: x86/mmu: Use page-track notifiers iff
 there are external users

Nit: there is a typo in the commit header: "iff" -> "if"

Line length is 81 characters. A little longer than 80 :)

> +static inline bool kvm_page_track_has_external_user(struct kvm *kvm) { return false; }
This line is also too long.
