- Subject: [PATCH tracing/kprobes 0/3] tracing/kprobes: kprobe-tracer updates
Hi Frederic,
Here is a few updates for kprobe-tracer which fix reported bugs and
is for catching up the latest ftrace.
- Use dynamic percpu profiling buffer patch is for catching up
the latest ftrace change.
- Checking the result of create_event_dir() patch improves ftrace
code pointed by Li Zefan (thanks!).
- Add VIA instructions to x86 insn decoder patch fixes decoding
bug reported by Ingo Molnar (thanks!).
Soon after this series, I'll send perf-kprobe patch series.
Thank you,
