Not at all; the kernel unmounts all filesystems, and then RF writes
out its parity clean status on last device close.

You just need to arrange for non-filesystem users of RF devices to
also let go of them in time; cgd, swap, stacked raid, etc.

Perhaps we could add an 'unconfigure-on-last-close' to cgd, or to
wedges more generally later.  A generic mechanism to publish stacking
tree information probably also belongs as part of wedges.
