Subject: [PATCHv3 bpf-next 4/9] selftests/bpf: Do not unload bpf_testmod in load_bpf_testmod
Date: Fri, 3 Feb 2023 17:23:31 +0100 [thread overview]
Message-ID: <20230203162336.608323-5-jolsa@kernel.org> (raw)
In-Reply-To: <20230203162336.608323-1-jolsa@kernel.org>
Do not unload bpf_testmod in load_bpf_testmod, instead call
unload_bpf_testmod separatelly.
This way we will be able use un/load_bpf_testmod functions
in other tests that un/load bpf_testmod module.
