From 8aff460f216753d86ab90ddbcab0125ab2400335 Mon Sep 17 00:00:00 2001 From: Aaron Lewis Date: Wed, 21 Sep 2022 15:15:24 +0000 Subject: KVM: x86: Add a VALID_MASK for the flags in kvm_msr_filter_range Add the mask KVM_MSR_FILTER_RANGE_VALID_MASK for the flags in the struct kvm_msr_filter_range. This simplifies checks that validate these flags, and makes it easier to introduce new flags in the future. No functional change intended.
