I send them to Andrew (Cc linux-kernel and/or linux-mm, erratic which,
at best depending on what the area of interest is - there's not much
of interest to linux-mm in the case of this unification) to get their
airing in -mm until the next merge window.

You could do that, or were you expecting me to pick up what you had?
We can do it that way too if you prefer: as things stood, I think
you were intending to add a patch to remove that redundant function,
and another to remove CONFIG_TMPFS - but I can do them if you prefer.
