Hi Linus,

Please pull the following Ceph updates for 3.2-rc1 from

  git://github.com/NewDreamNetwork/ceph-client.git for-linus
or
  git://ceph.newdream.net/git/ceph-client.git for-linus

(That's the old tree location.  I haven't reestablished korg access because
I don't see other kernel devs much around these parts.  Still working on it.)

The biggest thing here is a rewrite of the read path that vastly improves 
read(ahead) performance.  There is also optional support for server name 
resolution using the dns stuff, a fix for 32-bit ino number uniqueness, 
and a range of cleanups and small memory leak fixes.

Once Christoph picks up the fixed d_prune patch I'll have a few more 
patches to send you that trun some Ceph client-side dentry caching stuff 
back on.

Thanks!
sage
