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
