Help text

This allows the user to add tracing events (similar to tracepoints) on the fly via the ftrace interface. See Documentation/trace/kprobetrace.txt for more details.

Those events can be inserted wherever kprobes can probe, and record various register and memory values.

This option is also required by perf-probe subcommand of perf tools. If you want to use perf tools, this option is strongly recommended.
