Hold it. The real question here is which logics do we want there.
IOW, and how many device nodes do we want to appear and _when_ do
we want them to appear?
The when part is what looks to make it racy. I'm guessing that we're
relying on udev to create those loop nodes. If so, I think any scheme
that creates more on demand would give transient mount errors while
it's waiting on udev to create more nodes.
Perhaps if we were to start with 8 loop nodes at init (as we have in
2.6.21), and then always maintain a margin of 8 (or 4, or...) when
they start being used or detached?
