I don't understand either of the naming conventions here.  Doesn't
filesystem stuff go under the "vfs" node?

(No, I don't understand why, but it would be nice to be consistent,
at least)

Also, "syncfs" is not externally visible; it is just a (quite possibly
misnamed) directory with some code for the syncer in it.  Why expose
it now?
