Subject: [PATCH tip/core/rcu 0/2] RCU force_quiescent_state() fix and dyntick cleanup
Date: Wed, 28 Oct 2009 08:14:19 -0700 [thread overview]
Message-ID: <20091028151419.GA7838@linux.vnet.ibm.com> (raw)
This patch series contains a cleanup and a fix:
o Code cleanup from Lai Jiangshan that makes the calls to
rcu_irq_enter() and rcu_irq_exit() more obviously correct.
The previous code worked because rcu_irq_exit() is always
an empty function if !NO_HZ.
o Fix a low-probability race in the TREE_RCU infrastructure
that can be triggered by extremely long grace periods.
Thanx, Paul
