McKenney <paulmck@xxxxxxxxxxxxxxxxxx> AuthorDate: Mon, 22 Feb 2010 17:04:51 -0800 Committer: Ingo Molnar <mingo@xxxxxxx> CommitDate: Thu, 25 Feb 2010 10:34:47 +0100 sched: Better name for for_each_domain_rd As suggested by Peter Ziljstra, make better choice of name for for_each_domain_rd(), containing "rcu_dereference", given that it is but a wrapper for rcu_dereference_check(). The name rcu_dereference_check_sched_domain() does that and provides a separate per-subsystem name space. Signed-off-by: Paul E.
