Ceph fixes for 3.10.y

Ceph fixes for 3.10.y

[Sage Weil]

Hi Greg,

This is a somewhat long overdue set of fixes for 3.10.y.  Since there 
are a lot of patches, they can be pulled from

  git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-stable-3.10.24

If you prefer, I can send them as separate emails instead.  Note that this 
branch includes the 2 patches from the 3.12.y series you already picked 
up.

They are all reviewed, retested, and reference the original upstream 
commit (via git cherry-pick -x).

Thanks!
sage

I've applied all of these now, but please be careful when doing these
backports, your "cherrypicked from" lines didn't all match up with real
git ids in Linus's tree (hint look at the patches that had multiple
cherry-pick lines...)

thanks,

Hi Greg,

Sorry, it's my screw up.  I've rechecked, the following three commits
are affected:

  ceph: cleanup types in striped_read()
  ceph: fix bugs about handling short-read for sync read mode.
  ceph: allow sync_read/write return partial successed size of read/write.

The first "cherry picked from" line for all of those three commits is
correct, while the second of course is bogus.  It looks like
I accidentally cherry picked those commits twice: first to the testing
branch and then to the real for-stable.  Will be more careful in the
future!

Thanks,

                Ilya

I am also queuing those that were missing in the 3.11 kernel.  Thanks!
