From b9a49f8cb02f08592054b953adcacecd59b7ae4b Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 8 Dec 2022 19:28:58 -0300 Subject: perf tools: Check if libtracevent has TEP_FIELD_IS_RELATIVE Some distros have older versions of libtraceevent where TEP_FIELD_IS_RELATIVE and its associated semantics are not present, so we need to check if the version has it, it was introduced in libtraceevent 1.5.0.
