Hey Jens,

Please pull the following git tree in your 3.2 drivers tree:

git pull git://oss.oracle.com/git/kwilk/xen.git stable/for-jens-3.2

which has an exciting new feature - the discard ('feature-discard')
aka TRIM/UNMAP. Now they can be passed from the guest to the backend.

There is also a tiny cleanup patch.
