Paul E. McKenney 81e701e437 rcu: Add more debug info on "kthread starved" RCU CPU stall warnings
This commit adds grace number and command-flags information to the
"kthread starved" message that is sometimes printed out as part of
RCU CPU stall warnings.  This message is caused by the corresponding
RCU grace-period kthread not having run for at least two seconds, and
this added information can be helpful when debugging.
