Subject: [PATCH bpf-next 0/3] bpf: tracing_multi link info support
Date: Sun, 21 Jun 2026 22:45:21 +0200	[thread overview]
Message-ID: <20260621204524.61067-1-jolsa@kernel.org> (raw)

hi,
adding link info support for tracing_multi link.

Adding the kernel support with related selftests and bpftool support
to display the tracing_multi link info, the output looks like:

  # bpftool link
  ...
  27: tracing_multi  prog 93
          attach_type trace_fentry_multi  obj_id 1  count 3
          btf_id           addr             cookie           func [module]
          91984            ffffffff824f4a24 a                bpf_fentry_test1
          91986            ffffffff824f6a84 1e               bpf_fentry_test2
          91987            ffffffff824f6a94 14               bpf_fentry_test3
          pids test_progs(1462)

thanks,
jirka
