rcu: Detect stalls caused by failure to propagate up rcu_node tree If all CPUs have passed through quiescent states, then stalls might be due to starvation of the grace-period kthread or to failure to propagate the quiescent states up the rcu_node combining tree. The current stall warning messages do not differentiate, so this commit adds a printout of the root rcu_node structure's ->qsmask field. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
