XFS fixes needed in stable kernels

[Dave Chinner]

Hi Stable Kernel Gurus!

The following XFs fixes need to be pushed back to stable kernels.
The commits weren't all tagged in the recent 3.17-rc1 merge, so
you're getting an email from me instead. The commits required
from 3.17-rc1 are:

67dc288 xfs: ensure verifiers are attached to recovered buffers
5fd364f xfs: quotacheck leaves dquot buffers without verifiers
ad3714b xfs: dquot recovery needs verifiers

These are definitely needed for 3.16.y and 3.15.y, but aren't
critical for 3.14 and 3.13 because it only affects configurations
marked "experimetal: use at your own risk" and probably won't apply
easily. They aren't necessary at all for older kernels than
3.13....

Cheers,

Dave.
