tracing/kprobe: Add per-probe delete from event
Allow user to delete a probe from event. This is done by head match. For example, if we have 2 probes on an event $ cat kprobe_events p:kprobes/testprobe _do_fork r1=%ax r2=%dx p:kprobes/testprobe idle_fork r1=%ax r2=%cx Then you can remove one of them by passing the head of definition which identify the probe. $ echo "-:kprobes/testprobe idle_fork" >> kprobe_events Link: http://lkml.kernel.org/r/156095688848.28024.15798690082378432435.stgit@devnote2Signed-off-by: NMasami Hiramatsu <mhiramat@kernel.org> Signed-off-by: NSteven Rostedt (VMware) <rostedt@goodmis.org>
