Subject: [PATCH v6 bpf-next 01/17] selftests/bpf: fix RELEASE=1 build for tc_opts
Date: Wed, 1 Nov 2023 20:37:43 -0700	[thread overview]
Message-ID: <20231102033759.2541186-2-andrii@kernel.org> (raw)
In-Reply-To: <20231102033759.2541186-1-andrii@kernel.org>

Compiler complains about malloc(). We also don't need to dynamically
allocate anything, so make the life easier by using statically sized
buffer.
