Subject: [PATCH 28/29] tools lib traceevent: Add flags NOHANDLE and PRINTRAW to individual events

From: Steven Rostedt <srostedt@...hat.com>

Add the flags EVENT_FL_NOHANDLE and EVENT_FL_PRINTRAW to the event flags
to have the event either ignore the register handler or to ignore the
handler and also print the raw format respectively.

This allows a tool to force a raw format or non handle for an event.
