Subject: [PATCH 02/31] KVM: selftests: Take into account mixed memory fault flags
Date: Fri, 18 Sep 2026 09:50:01 -0400	[thread overview]
Message-ID: <20260918135030.171564-3-pbonzini@redhat.com> (raw)
In-Reply-To: <20260918135030.171564-1-pbonzini@redhat.com>

From: Nicolas Saenz Julienne <nsaenz@amazon.com>

Update x86_64/private_mem_kvm_exits_test to take into account memory
fault flags might contain multiple bits set while remaining valid---for
example KVM might return KVM_MEMORY_EXIT_FLAG_READ in addition to
KVM_MEMORY_EXIT_FLAG_PRIVATE.
