[GIT PULL] Ceph fixes for 2.6.34-rc3

[Sage Weil]

Hi Linus,

Please pull the current set of Ceph fixes for 2.6.34-rc3 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus

There are a lot of bug fixes here, accumulated since the original pull 
request was sent during the merge window.  A few client hangs, some 
oopses, authentication fixes, and failure handling fixes.  There are also 
a handful of cleanups mixed in here that didn't seem worth untangling from 
the bug fixes, as well as some documentation updates that should make it 
into 2.6.34.

I'm assuming I should send these to you sooner rather than later, although 
if you prefer a consolidated pull later in the cycle I can do that too.

Also, thanks for pulling Ceph into your tree!  It's already making a 
difference in terms of code review and testing.

Thanks-
sage
