Hi,
Here is a series of updating kprobe-based dynamic event for
supporting soft-disabling mode and multiple buffers.
This also has some bugfixes of ftrace which I found
including an important deadlock fix.
I think uprobe-based events can also support multi-buffer
and soft-disabling as I did in this series.
