Subject: [PATCH tip/core/rcu 3/4] rcu: rename dynticks_completed to completed_fqs

From: Paul E. McKenney <paulmck@...ux.vnet.ibm.com>

This field is used whether or not CONFIG_NO_HZ is set, so the old name
of ->dynticks_completed is quite misleading.  Change to ->completed_fqs,
given that it the value that force_quiescent_state() is trying to drive
the ->completed field away from.

Signed-off-by: Paul E. McKenney <paulmck@...ux.vnet.ibm.com>
