[GIT PULL] Ceph updates for 3.1-rc1

[Sage Weil]

Hi Linus,

Please pull the following Ceph updates from

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

Lots of different things here.  There is some code cleanup with the file 
flags, a few snapshot metadata writeback fixes, a fix for unnecessary 
timeouts on heavily loaded clusters, and a fix for dentry leases.  There 
are many fixes for bugs Al turned up: a fix and cleanup in the open intent 
code, and several fixes for d_parent use without the appropriate locks (a 
full code audit caught a few more).  RBD devices now clean up on the 
server when they are unmapped, rbd request sizes are now larger, and the 
ceph readahead window is set up properly.

Thanks!
sage
