rcu: Make RCU_FANOUT_LEAF help text more explicit about skew_tick If you set RCU_FANOUT_LEAF too high, you can get lock contention on the leaf rcu_node, and you should boot with the skew_tick kernel parameter set in order to avoid this lock contention. This commit therefore upgrades the RCU_FANOUT_LEAF help text to explicitly state this. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
