Subject: [PATCH v5 net-next 05/12] selftests/bpf: rewrite test_align
Date: Mon, 7 Aug 2017 15:27:34 +0100 [thread overview]
Message-ID: <1616facf-7cf2-3f9f-4147-02f932498223@solarflare.com> (raw)
In-Reply-To: <ad840039-8d4a-b2a9-b2eb-a8f079926b53@solarflare.com>
Expectations have changed, as has the format of the logged state.
To make the tests easier to read, add a line-matching framework so that
each match need only quote the register it cares about. (Multiple
matches may refer to the same line, but matches must be listed in
order of increasing line.)
