Subject: [PATCH bpf-next 08/13] bpf/tests: Add test case flag for verifier zero-extension
Date: Thu,  2 Sep 2021 20:52:24 +0200	[thread overview]
Message-ID: <20210902185229.1840281-9-johan.almbladh@anyfinetworks.com> (raw)
In-Reply-To: <20210902185229.1840281-1-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.
