Subject: [PATCH 00/26] Convert locks that can't sleep in -rt to raw_spinlock
Date: Mon, 11 Jan 2010 22:26:30 +0100 [thread overview]
Message-ID: <1263245216-14754-1-git-send-email-jkacur@redhat.com> (raw)
Thomas:
Now that your changes that free up the raw_spinlock name are upstream.
(described below for other readers)
http://lwn.net/Articles/365863/
http://lwn.net/Articles/366608/
I wanted to forward port the preempt-rt patches that convert locks to
atomic_spinlocks (rt tree only) to the new scheme.
The patches below are a result of that effort.
Please queue these up for 2.6.34 upstream, and please pull for preempt-rt
You can pull them from
git://git.kernel.org/pub/scm/linux/kernel/git/jkacur/jk-2.6.git
jk/v2.6.33-rc3-raw-spinlocks
Thanks
