Subject: [PATCH v4 bpf-next 10/12] selftests/bpf: re-generate vmlinux.h and BPF skeletons if bpftool changed
Date: Thu, 18 Mar 2021 12:40:34 -0700	[thread overview]
Message-ID: <20210318194036.3521577-11-andrii@kernel.org> (raw)
In-Reply-To: <20210318194036.3521577-1-andrii@kernel.org>

Trigger vmlinux.h and BPF skeletons re-generation if detected that bpftool was
re-compiled. Otherwise full `make clean` is required to get updated skeletons,
if bpftool is modified.

Fixes: acbd06206bbb ("selftests/bpf: Add vmlinux.h selftest exercising tracing of syscalls")
