Subject: [PATCH bpf-next 1/9] selftests/bpf: prevent headers to be compiled as C code
Date: Fri, 26 Jul 2019 13:37:39 -0700	[thread overview]
Message-ID: <20190726203747.1124677-2-andriin@fb.com> (raw)
In-Reply-To: <20190726203747.1124677-1-andriin@fb.com>

Apprently listing header as a normal dependency for a binary output
makes it go through compilation as if it was C code. This currently
works without a problem, but in subsequent commits causes problems for
differently generated test.h for test_progs. Marking those headers as
order-only dependency solves the issue.
