Subject: [PATCH tip/core/rcu 0/2] rcu: lastcomp cleanups, fix rcu_pending() false positives
Date: Fri, 13 Nov 2009 19:51:00 -0800	[thread overview]
Message-ID: <20091114035100.GA9599@linux.vnet.ibm.com> (raw)

These two patches are yet more from the ongoing cleanup/inspection
session for RCU.

1.	Get the (hopefully) last of the accesses to the ->completed
	fields cleaned up.

2.	Fix a race in __rcu_pending() accesses to ->gpnum and
	->completed fields that could cause needless (but otherwise
	harmless) raising of RCU_SOFTIRQ.
