Subject: [PATCH] selftests: adopt BPF's approach to quieter builds
Date: Thu, 11 Apr 2024 12:05:34 -0700	[thread overview]
Message-ID: <20240411190534.444918-1-kuba@kernel.org> (raw)

selftest build is fairly noisy, it's easy to miss warnings.
It's standard practice to add alternative messages in
the Makefile. I was grepping for existing solutions,
and found that bpf already has the right knobs.

Move them to lib.mk and adopt in net.
Convert the basic rules in lib.mk.

Signed-off-by: Jakub Kicinski <kuba@kernel.org>

If this is okay with everyone, can we possibly apply it to net-next?
