This is a constant increase, where\nnew tracepoints will not increase the Text. But the big drop is\nin the data size (as well as needed allocations to hold the fields).\nThis will give even more savings as more tracepoints are created.\n\nNote, if just TRACE_EVENT()s are used and not DECLARE_EVENT_CLASS()\nwith several DEFINE_EVENT()s, then the savings will be lost. But\nwe are pushing developers to consolidate events with DEFINE_EVENT()\nso this should not be an issue.\n\nThe kprobes define a unique class to every new event, but are dynamic\nso it should not be a issue.\n\nThe syscalls however have a single class but the fields for the individual\nevents are different. The syscalls use a metadata to define the\nfields. I moved the fields list from the event to the metadata and\nadded a \"get_fields()\" function to the class. This function is used\nto find the fields. For normal events and kprobes, get_fields() just\nreturns a pointer to the fields list_head in the class. For syscall\nevents, it returns the fields list_head in the metadata for the event.\n\nv2: Fixed the syscall fields. The syscall metadata needs a list\n of fields for both enter and exit.\n\nAcked-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nAcked-by: Mathieu Desnoyers
