| |
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
