From 4bcfe055030d9e953945def3864f7e6997b27782 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 10 Nov 2009 13:37:21 -0800 Subject: [PATCH] rcu: Rename dynticks_completed to completed_fqs 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.
