Hmm. I'm adding a few more people and linux-fsdevel to the reply,
because we had a number of filesystems remove writepages use lately,
including some that did it as a fix after the merge window.

Everybody involved seemed to claim it was just a no-brainer
switch-over, and I just took that on faith. Now it looks like that
wasn't true at least for gfs2 due to different semantics.

Maybe the gfs2 issue is purely because of how gfs2 did the conversion
(generic_writepages -> filemap_fdatawrite_wbc), but let's make people
look at their own cases.
