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
