Commit Message

Ian Rogers Jan. 11, 2023, 7:06 a.m. UTC 
  Switch HAVE_LIBTRACEEVENT_TEP_FIELD_IS_RELATIVE to be a version number
test on libtraceevent being >= to version 1.5.0. This also corrects a
greater-than test to be greater-than-or-equal.

Discussed here:
https://lore.kernel.org/lkml/20221205225940.3079667-3-irogers@google.com/

Fixes: b9a49f8cb02f ("perf tools: Check if libtracevent has TEP_FIELD_IS_RELATIVE")

Ping. Remove one ifdef in favor of a consistent version check, gets
debug logging from libtraceevent going.

Thanks,
Ian
