tracing: Add comments for the other bits of ftrace_event_call.flags
TRACE_EVENT_FL_ENABLED_BIT, TRACE_EVENT_FL_FILTERED_BIT, TRACE_EVENT_FL_RECORDED_CMD_BIT, Have comments about what they are, but: TRACE_EVENT_FL_CAP_ANY_BIT, TRACE_EVENT_FL_NO_SET_FILTER_BIT, TRACE_EVENT_FL_IGNORE_ENABLE_BIT, do not, making them second class citizens. To prevent another class warfare, these bits have protested for their right to be commented. And By Golly! I'll give them what they want! Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
