Subject: perf ordered_events: Add ordered_events__last_flush_time()
X-Git-Tag: v6.0-rc1~95^2~141
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f8bcf1e223ad08a4f0d45369a749c58c9bcd5f3c;p=thirdparty%2Fkernel%2Flinux.git

perf ordered_events: Add ordered_events__last_flush_time()

Allow callers to get the ordered_events last flush timestamp.

This is needed in perf inject to obey finished-round ordering when
injecting additional events (e.g. from a guest perf.data file) with
timestamps. Any additional events that have timestamps before the last
flush time must be injected before the corresponding FINISHED_ROUND event.
