Subject: [PATCH bpf-next v3 01/18] bpf: Drop process_timer_func wrappers
Date: Sat, 1 Aug 2026 00:46:16 -0700 [thread overview]
Message-ID: <20260801074633.1595644-2-ameryhung@gmail.com> (raw)
In-Reply-To: <20260801074633.1595644-1-ameryhung@gmail.com>
Drop process_timer_{helper,kfunc}() since bpf_call_arg_meta is now
shared by helper and kfunc. Call process_timer_func() directly.
