Subject: [PATCH tip/core/rcu 0/2] rcu: fixes for RCU lockdep
Date: Thu, 25 Feb 2010 14:06:24 -0800 [thread overview]
Message-ID: <20100225220624.GA7013@linux.vnet.ibm.com> (raw)
Hello!
This set fixes a couple of problems with the RCU-based lockdep patches:
1. Make the lockdep_rcu_dereference() message less alarmist
2. Make rcu_read_lock_sched_held() take boot-time lack of
preemption into account.
Thanx, Paul
