-Subject: perf test: Don't leak workload gopipe in PERF_RECORD_*
-
-From: Ian Rogers <irogers@google.com>
-
-[ Upstream commit 48918cacefd226af44373e914e63304927c0e7dc ]
-
-The test starts a workload and then opens events. If the events fail
-to open, for example because of perf_event_paranoid, the gopipe of the
-workload is leaked and the file descriptor leak check fails when the
-test exits. To avoid this cancel the workload when opening the events
-fails.
