Subject: [PATCH bpf-next 09/17] bpf: move kfunc_call_arg_meta higher in the file
Date: Thu, 2 Mar 2023 15:50:07 -0800 [thread overview]
Message-ID: <20230302235015.2044271-10-andrii@kernel.org> (raw)
In-Reply-To: <20230302235015.2044271-1-andrii@kernel.org>
Move struct bpf_kfunc_call_arg_meta higher in the file and put it next
to struct bpf_call_arg_meta, so it can be used from more functions.
