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
