Too subtle for me.
And is it? Because mnt is from
mnt = real_mount(path->mnt);
earlier, while vfsmount is plain "path->mnt".

Leftover. Good catch.

No arguments against that - I tried to keep it with the same structure it had when it was inside prepend_path().
Which I obviously wasn't very good at (see your fixes above ;), but it was *meant* to be a minimal patch with no structural change.
