+Subject: [PATCH] lttng-ust:Fix live timer calculation error
+
+There is an calculation error for live timer. Variable chan->switch_timer_interval is
+based on microsecond, and it is not right to assign chan->switch_timer_interval mod
+1000000 to var tv_nsec which is based on nanosecond.
+
+Upstream-Status: Pending
