[PATCH 0/4] tracing: cleanup trace event macro

[Wei Yang]

TRACE_EVENT definition is some kind of magic. We define/un-define some
elements to implement it.

During the code reading, I found there are some redundant definition of the
macro. Let's reform and remove some of them.

Wei Yang (4):
  tracing: not necessary to undefine DEFINE_EVENT again
  tracing: not necessary re-define DEFINE_EVENT_PRINT
  tracing: define DEFINE_EVENT_PRINT not related to DEFINE_EVENT
  tracing: not necessary to define DEFINE_EVENT_PRINT to be empty again
