rcu: Rename qs_pending to core_needs_qs
An upcoming commit needs to invert the sense of the ->passed_quiesce rcu_data structure field, so this commit is taking this opportunity to clarify things a bit by renaming ->qs_pending to ->core_needs_qs. So if !rdp->core_needs_qs, then this CPU need not concern itself with quiescent states, in particular, it need not acquire its leaf rcu_node structure's ->lock to check. Otherwise, it needs to report the next quiescent state. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
