Subject: [PATCH bpf-next 0/2] libbpf: allow users to set kprobe/uprobe attach mode

From: Menglong Dong <imagedong@...cent.com>

By default, libbpf will attach the kprobe/uprobe eBPF program in the
latest mode that supported by kernel. In this series, we add the support
to let users manually attach kprobe/uprobe in legacy or perf mode in the
1th patch.

And in the 2th patch, we add the selftests for it.

*** BLURB HERE ***

  libbpf: add support to set kprobe/uprobe attach mode
  selftests/bpf: add test for legacy/perf kprobe/uprobe attach mode
