[RFC][RT][PATCH 0/4] rtmutex: Simplify PI code

[Steven Rostedt]

This is still a little buggy. I've been hitting a hang when running
dbench 100 in a loop. But I also hit that hang with vanilla -rt.

But I'm sure this still has some things that need to be straighten out.
Anyway, you can either apply the following patches or pull the code
from the listed git repo.

This still needs to be worked out, but since I'm taking off for the
rest of the year, I might as well show you where I ended up at.

The following patches are in:

  git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-rt.git

    branch: rt/tip/rt/devel


Lai Jiangshan (1):
      rtmutex: Ensure only the top waiter or higher priority task can take the lock

Steven Rostedt (3):
      rtmutex: Only save lock depth once in spin_slowlock
      rtmutex: Try to take lock early in rt_spin_lock_slowlock()
      rtmutex: Revert Optimize rt lock wakeup
