Subject: [PATCH tracing/kprobes 0/6] tracing/kprobes: kprobe-based event
	tracer update and perf support

Hi,

Here are bugfixes for kprobe-based event tracer. Thank you for review
and reporting bugs! I fixed it. And also I decided to disable
kprobe event when defining, since the events outputs may suddenly
mess up the ftrace ring_buffer.

Frederic, could you see the patch 4/6? which is what I said on the
previous threads.


Thank you,
