Thanks a lot for including tmpfs in your enhancements,
and mercifully I don't have to worry much about on-disk compatibility :)
but even so I share Richard's point of view: if Christoph has some
alignment in mind here, then I don't see why the rush to push something
else in right now - and the 0day robot seems to agree that it's rushed.

A welcome addition to tmpfs once fs is agreed on the way to go - thanks.
