  "message": "perf evsel: Cache associated event_format\n\nWe already lookup the associated event_format when reading the perf.data\nheader, so that we can cache the tracepoint name in evsel-\u003ename, so do\nit a little further and save the event_format itself, so that we can\navoid relookups in tools that need to access it.\n\nChange the tools to take the most obvious advantage, when they were\nusing pevent_find_event directly. More work is needed for further\nremoving the need of a pointer to pevent, such as when asking for event\nfield values (\"common_pid\" and the other common fields and per\nevent_format fields).\n\nThis is something that was planned but only got actually done when\nAndrey Wagin needed to do this lookup at perf_tool-\u003esample() time, when\nwe don\u0027t have access to pevent (session-\u003epevent) to use with\npevent_find_event().\n\nCc: Andrey Wagin \u003cavagin@gmail.com\u003e\nCc: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Jiri Olsa \u003cjolsa@redhat.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Namhyung Kim \u003cnamhyung@gmail.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nLink: http://lkml.kernel.org/n/tip-txkvew2ckko0b594ae8fbnyk@git.kernel.org\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n",
