rcu: Make RCU_CPU_STALL_INFO include number of fqs attempts One way that an RCU CPU stall warning can happen is if the grace-period kthread is not allowed to execute. One proxy for this kthread's forward progress is the number of force-quiescent-state (fqs) scans. This commit therefore adds the number of fqs scans to the RCU CPU stall warning printouts when CONFIG_RCU_CPU_STALL_INFO=y. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
