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.
