From: Paul E. McKenney <paulmck <at> linux.vnet.ibm.com>
Subject: [PATCH tip/core/rcu 0/13] rcu: add lockdep checking, doc update, dyntick GP acceleration
Newsgroups: gmane.linux.kernel
Date: Friday 12th February 2010 00:00:16 UTC (over 6 years ago)
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.
