David Matlack 6ff94f27fd KVM: x86/mmu: Improve TLB flush comment in kvm_mmu_slot_remove_write_access() ... Rewrite the comment in kvm_mmu_slot_remove_write_access() that explains why it is safe to flush TLBs outside of the MMU lock after write-protecting SPTEs for dirty logging. The current comment is a long run-on sentence that was difficult to understand. In addition it was specific to the shadow MMU (mentioning mmu_spte_update()) when the TDP MMU has to handle this as well. The new comment explains: - Why the TLB flush is necessary at all. - Why it is desirable to do the TLB flush outside of the MMU lock. - Why it is safe to do the TLB flush outside of the MMU lock. No functional change intended.
