Subject: bpftool: Show also the name of type BPF_OBJ_LINK
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7a255ae77216237a4ce83ddea595aa4e0a812f46;p=linux.git

bpftool: Show also the name of type BPF_OBJ_LINK

For example, /sys/fs/bpf/maps.debug is a BPF link. When you run `bpftool map show`
to show it:

Before:

  $ bpftool map show pinned /sys/fs/bpf/maps.debug
  Error: incorrect object type: unknown

After:

  $ bpftool map show pinned /sys/fs/bpf/maps.debug
  Error: incorrect object type: link
