In the meantime, on a VFS level, we got rid of the "rename2" naming,
and now the plain regular rename is the extended version.

There's a few other filesystems using "rename2" as a name for the now
no longer true historical reasons, but I noticed it particularly in
this pull request because I fixed up a trivial conflict around that
area.

You might consider renaming it, or just put the "rename2" logic into
the regular rename function, but whatever. It doesn't really _matter_,
it's just an odd naming artifact.

(I've not pushed out my merge yet, it's still going through the build
tests etc, but I thought I'd mention this detail).
