Subject: [PATCH bpf-next v1 6/9] libbpf: Add sleepable tp_btf
Date: Fri, 25 Feb 2022 15:43:36 -0800 [thread overview]
Message-ID: <20220225234339.2386398-7-haoluo@google.com> (raw)
In-Reply-To: <20220225234339.2386398-1-haoluo@google.com>
In the previous patches, we have introduced sleepable tracepoints in the
kernel and listed a couple of cgroup tracepoints as sleepable. This
patch introduces a sleepable version of tp_btf. Sleepable tp_btf progs
can only attach to sleepable tracepoints.
