[PATCH 0/2] KVM: x86/mmu: Fix a TDP MMU leak and optimize zap all

From: Sean Christopherson
Date: Thu Aug 12 2021 - 01:07:25 EST


Patch 1 fixes a leak of root-1 shadow pages, patch 2 is a minor
optimization to the zap all flow that avoids re-reading and re-checking
the root-1 SPTEs after they've been zapped by "zap all" flows.

Sean Christopherson (2):
KVM: x86/mmu: Don't skip non-leaf SPTEs when zapping all SPTEs
KVM: x86/mmu: Don't step down in the TDP iterator when zapping all
SPTEs
