Some of the event triggers can run fine in an instance. Have them tested in one as well. The ones that still need work are the snapshot, stacktrace and traceon/off triggers, as they don't currently pass a handle to the trace_array they are attached to. But that can be for a future project. Acked-by: Masami Hiramatsu <mhiramat@kernel.org> Acked-by: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
