[PATCH] KVM: x86/mmu: kvm_faultin_pfn has to return false if pfh is returned

From: Andrei Vagin
Date: Fri Oct 15 2021 - 12:32:55 EST


This looks like a typo in 8f32d5e563cb. This change didn't intend to do
any functional changes.

The problem was caught by gVisor tests.

Fixes: 8f32d5e563cb ("KVM: x86/mmu: allow kvm_faultin_pfn to return page fault handling code")
