This collides in non-trivial ways with the always-coming-never-arrives
r-o-bind-mounts patches.

I have an old version of those patches in -mm and I believe that Al
is/was/has set up some git tree with these patches and perhaps other stuff.

So some coordination is required please. I'd suggest that if Al indeed
does have such a tree, he hand over the URL so I can get it into -mm and
that you then redo these patches on top of that.

Please also Cc Al and Christoph on these patches, as they are hitting files
which they maintain and develop.
