From: Hou Tao <houtao1@huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I53R0H CVE: NA backport: openEuler-22.03-LTS --------------------------- Identify writable tracepoint program by section prefix raw_tracepoint.w/. The correct way is back-porting from commit ccaf12d6215a ("libbpf: Support detecting and attaching of writable tracepoint program"), but the refactoring of libbpf makes it hard, so using the same section prefix as ccaf12d6215a and post a home-made patch instead.
