Subject: [PATCH v2] bpf: fix build warning - missing prototype
Date: Tue, 24 Mar 2020 08:22:31 +0100 [thread overview]
Message-ID: <20200324072231.5780-1-jpmenil@gmail.com> (raw)
In-Reply-To: <7c27e51f-6a64-7374-b705-450cad42146c@fb.com>
Fix build warnings when building net/bpf/test_run.o with W=1 due
to missing prototype for bpf_fentry_test{1..6}.
Declare prototypes in order to silence warnings.
