Subject: [PATCH tip/core/rcu 0/13] rcu: add lockdep checking, doc update, dyntick GP acceleration
Date: Thu, 11 Feb 2010 16:00:16 -0800	[thread overview]
Message-ID: <20100212000016.GA25781@linux.vnet.ibm.com> (raw)

Hello!

The first 11 patches extend lockdep to check for proper protection
of rcu_dereference(), described in http://lwn.net/Articles/371986/,
and apply these lockdep extensions in a number of areas in the kernel.
There are likely more such changes required, as I am limited to those
located by the systems I have access to.

The twelfth patch is a documentation update, and the last patch
accelerates grace periods when the current CPU is the last
non-dyntick-idle CPU in the system, which is important for some
multi-core battery-powered devices.
