Subject: [patch] perf_event_open.2: add PERF_SAMPLE_BRANCH_CALL branch sample type
Date: Fri, 21 Oct 2016 16:55:21 -0400 (EDT) [thread overview]
Message-ID: <alpine.DEB.2.20.1610211653160.12619@macbook-air> (raw)
Linux 4.4 (c229bf9dc179d2023e185c0f705bdf68484c1e73) added
the PERF_SAMPLE_BRANCH_CALL branch sample type, which confusingly
is a direct-call only subset of what PERF_SAMPLE_BRANCH_ANY_CALL
provides.
