  "message": "tracing: Add DEFINE_EVENT_FN() macro\n\nEach TRACE_EVENT() adds several helper functions. If two or more trace events\nshare the same structure and print format, they can also share most of these\nhelper functions and save a lot of space from duplicate code. This is why the\nDECLARE_EVENT_CLASS() and DEFINE_EVENT() were created.\n\nSome events require a trigger to be called at registering and unregistering of\nthe event and to do so they use TRACE_EVENT_FN().\n\nIf multiple events require a trigger, they currently have no choice but to use\nTRACE_EVENT_FN() as there\u0027s no DEFINE_EVENT_FN() available. This unfortunately\ncauses a lot of wasted duplicate code created.\n\nBy adding a DEFINE_EVENT_FN(), these events can still use a\nDECLARE_EVENT_CLASS() and then define their own triggers.\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nLink: http://lkml.kernel.org/r/51C3236C.8030508@hds.com\nSigned-off-by: Seiji Aguchi \u003cseiji.aguchi@hds.com\u003e\nSigned-off-by: H.
