	Add a generic method to remove event from dynamic event list. This is same as other system under ftrace. You just need to pass the event name with '!', e.g. # echo p:new_grp/new_event _do_fork > dynamic_events This creates an event, and # echo '!p:new_grp/new_event _do_fork' > dynamic_events Or, # echo '!p:new_grp/new_event' > dynamic_events will remove new_grp/new_event event. Note that this doesn't check the event prefix (e.g. "p:") strictly, because the "group/event" name must be unique.

2018-12-08	tracing: Add unified dynamic event framework	Masami Hiramatsu
	Add unified dynamic event framework for ftrace kprobes, uprobes and synthetic events. Those dynamic events can be co-exist on same file because those syntax doesn't overlap. This introduces a framework part which provides a unified tracefs interface and operations.
