Why are these changes here instead of the previous commit (jbd2: add
fast commit machinery)?

Also, this is going to conflcit with Mauricio's data=journal patches,
which you'll notice when you rebase these patches on the current dev branch.
(The dev branch temporarily had your v9 patches merged in, so we could
get the test bots to comment on your changes, but I've since pulled
the fc patches back out.)
