====================
bpf: Add link_info support for uprobe multi link

hi,
this patchset adds support to get bpf_link_info details for
uprobe_multi links and adding support for bpftool link to
display them.

v4 changes:
  - move flags field up in bpf_uprobe_multi_link [Andrii]
  - include zero terminating byte in path_size [Andrii]
  - return d_path error directly [Yonghong]
  - use SEC(".probes") for semaphores [Yonghong]
  - fix ref_ctr_offsets leak in test [Yonghong]
  - other smaller fixes [Yonghong]

thanks,
jirka
