Al,
 would you mind taking a look at this part:

It doesn't look huge to me, and I don't care all that deeply about
configfs, and honestly, I'm not seeing huge amounts of actual
development there, with recent commits all being about cleanup of vfs
changes (eg things like the new idmapping changes etc).

That said, I really don't want to pull that with some core sanity checking.

So Al, do you see anything horrendous in how that configfs thing uses
a rename to do kind of an "atomic swap" of configfs state?
