Subject: [announce] rcu-walk and dcache scaling tree update

I'm rebasing the tree, because I don't expect anybody to be basing
downstream work on it, I hope that doesn't cause anybody pain.

Git tree is here:

git://git.kernel.org/pub/scm/linux/kernel/git/npiggin/linux-npiggin.git

Branch is:

vfs-scale-working

Changes since last posting:
* Added mntget/mntput scaling patch. I think this is important for
testers because it significantly increases parallelism through the
dcache and path walk. So both performance and races will get better
test coverage.
* Missing vfs.txt documentation for new _rcu dentry and inode ops.
* Large improvements to Documentation/filesystems/path-walk.txt
* Improved some changelogs
* Added AMD fam10h numbers to ``memcmp optimisation'' changelog, and
Westmere numbers to ``prefetch inode'' optimisation changelog. The
AMD doesn't get such a big boost as the Intel CPU when avoiding rep
cmp, but does get a small improvement.

Thanks,
Nick
