bpf, linux-kselftest, lkml, llvm
Subsystem:
bpf [general] (safe dynamic programs and tools), bpf [selftests] (test runners & infrastructure), kernel selftest framework, the rest · Maintainers:

Some functions is recursive for the kprobe_multi and impact the benchmark results. So just skip them. Signed-off-by: Menglong Dong <redacted> --- tools/testing/selftests/bpf/trace_helpers.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+)
