+Subject: [PATCH] tests: wait some more before analysing traces or starting
+ tracing
+
+Otherwise, there are sporadic race failures where lttng tracing
+is stopped before all expected events are collected or is started too soon, e.g.:
+
+PASS: tools/tracker/test_event_tracker 205 - Traced application stopped.
+PASS: tools/tracker/test_event_tracker 206 - Stop lttng tracing for session
+PASS: tools/tracker/test_event_tracker 207 - Destroy session tracker
+FAIL: tools/tracker/test_event_tracker 208 - Validate empty trace
+
+PASS: ust/namespaces/test_ns_contexts_change 42 - Stop lttng tracing for session mnt_ns
+PASS: ust/namespaces/test_ns_contexts_change 43 - Destroy session mnt_ns
+PASS: ust/namespaces/test_ns_contexts_change 44 - Wait after kill session daemon
+PASS: ust/namespaces/test_ns_contexts_change 45 - Validate trace for event mnt_ns = 4026531840, 1000 events
+PASS: ust/namespaces/test_ns_contexts_change 46 - Read a total of 1000 events, expected 1000
+PASS: ust/namespaces/test_ns_contexts_change 47 - Validate trace for event mnt_ns = 4026532303, 233 events
+FAIL: ust/namespaces/test_ns_contexts_change 48 - Read a total of 233 events, expected 1000
+
+This is a hack; issue should be fixed upstream with explicit syncs.
+It has been reported here: https://bugs.lttng.org/issues/1217
+
+Upstream-Status: Inappropriate [needs a real fix]
