Thanks a lot for the patch. I'd assume we want something slightly more clever even, similar to Paul's d78bca729.

Please beware that it's usually not a good idea to post patches that span multiple subtrees. I don't want to apply a patch to my kvm tree that touches jffs2 for example, as that's out of my scope. It usually makes a maintainer's life easier if you split up a patch like this according to tree responsibilities.
