Subject: [PATCH bpf-next v2 08/13] bpf/tests: Add test case flag for verifier zero-extension
Date: Wed, 8 Sep 2021 00:23:34 +0200 [thread overview]
Message-ID: <20210907222339.4130924-9-johan.almbladh@anyfinetworks.com> (raw)
In-Reply-To: <20210907222339.4130924-1-johan.almbladh@anyfinetworks.com>
This patch adds a new flag to indicate that the verified did insert
zero-extensions, even though the verifier is not being run for any
of the tests.
