From 7533377215b6ee432c06c5855f6be5d66e694e46 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Sat, 20 Nov 2021 01:50:08 +0000 Subject: KVM: x86/mmu: Use yield-safe TDP MMU root iter in MMU notifier unmapping Use the yield-safe variant of the TDP MMU iterator when handling an unmapping event from the MMU notifier, as most occurences of the event allow yielding.
