Let me list a patch-wise brief changelog.

patch 1/7:- Introduced dummy version of is_sdt_event() which always return false
             if !HAVE_LIBELF_SUPPORT.

patch 2/7: - is new. A new option introduced in this patch helps to passcustom
             data from builtin-*.c to libperf.

patch 3/7: - Removed direct calls from libperf to builtin-record.c which was used
             to prepare record.sdt_event_list. Instead pass list to libperf and let
             libperf manage it.

           - Introduce new wrapper func record__parse_events_option() that can
             differentiate between sdt and other events while parsing them in
             perf record.

           - Moved all functions from util/probe-file.c to util/probe-event.c
             which operates on perf_probe_event.

           - Merged 2nd and 4th patch of v4 into this patch.

           - Made free_sdt_list() static as it's only used inside util/probe-event.c.

patch 4/7:- Removed direct calls from libperf to builtin-record.c which was used
             to prepare record.sdt_event_list. Instead pass list to libperf and let
             libperf manage it.

           - Moved all functions from util/probe-file.c to util/probe-event.c
             which operates on perf_probe_event.

patch 5/7: No changes

patch 6/7: No changes

patch 7/7: No changes

Let me know if you need more details.

Thanks,
Ravi
