Subject: [PATCH 08/45] selftests: kvm: drop TEST_ASSERT_SUPPORTED_ATTRIBUTES
Date: Mon,  2 Nov 2026 12:40:52 -0500	[thread overview]
Message-ID: <20261102174130.8779-9-pbonzini@redhat.com> (raw)
In-Reply-To: <20261102174130.8779-1-pbonzini@redhat.com>

TEST_ASSERT_SUPPORTED_ATTRIBUTES() is supposedly reminding tha
__vm_set_memory_attributes() does not support multiple attributes, but
that is not really a problem; the tests need to know that multiple
attributes can be overwritten, but that is not a problem for a simple
wrapper around KVM_SET_MEMORY_ATTRIBUTES.
