117 The RCU, RCU-sched, and RCU-tasks implementations have CPU stall warning.
188 This boot/sysfs parameter controls the RCU-tasks stall warning
189 interval. A value of zero or less suppresses RCU-tasks stall
191 in seconds. An RCU-tasks stall warning starts with the line:
193 INFO: rcu_tasks detected stalls on tasks:
196 task stalling the current RCU-tasks grace period.
202 For non-RCU-tasks flavors of RCU, when a CPU detects that some other

213 PREEMPT_RCU builds can be stalled by tasks as well as by CPUs, and that
214 the tasks will be indicated by PID, for example, "P3421". It is even
215 possible for an rcu_state stall to be caused by both CPUs *and* tasks,
216 in which case the offending CPUs and tasks will all be called out in the list.
