Subject: [PATCH bpf-next v3 1/2] bpf: allow kfuncs within tracepoint and perf event programs
Date: Thu, 5 Sep 2024 15:38:11 -0700 [thread overview]
Message-ID: <20240905223812.141857-2-inwardvessel@gmail.com> (raw)
In-Reply-To: <20240905223812.141857-1-inwardvessel@gmail.com>
Associate tracepoint and perf event program types with the kfunc tracing
hook. This allows calling kfuncs within these types of programs.
