Subject: [PATCH bpf-next 0/3] samples: bpf: refactor kprobe tracing progs with libbpf
Date: Tue, 12 May 2020 23:43:36 +0900	[thread overview]
Message-ID: <20200512144339.1617069-1-danieltimlee@gmail.com> (raw)

Currently, the kprobe BPF program attachment method for bpf_load is
pretty outdated. The implementation of bpf_load "directly" controls and
manages(create, delete) the kprobe events of DEBUGFS. On the other hand,
using using the libbpf automatically manages the kprobe event.
(under bpf_link interface)

This patchset refactors kprobe tracing programs with using libbpf API
for loading bpf program instead of previous bpf_load implementation.
