Subject: [PATCH bpf-next 3/3] bpftool: print the comm of the process that loaded the program
Date: Fri, 11 Oct 2019 09:21:24 -0700
Message-ID: <20191011162124.52982-3-sdf@google.com> (raw)
In-Reply-To: <20191011162124.52982-1-sdf@google.com>

Print recently added created_by_comm along the existing created_by_uid.

Example with loop1.o (loaded via bpftool):
4: raw_tracepoint  name nested_loops  tag b9472b3ff5753ef2  gpl
        loaded_at 2019-10-10T13:38:18-0700  uid 0  comm bpftool
        xlated 264B  jited 152B  memlock 4096B
        btf_id 3
