Thanks! I think this turned out to be a lot cleaner too.

For filesystems that use filemap_write_and_wait_range today this now
becomes a pretty straight conversion to file_write_and_wait_range -- one
liner patches for the most part.

I've started rolling patches to do that, but now I'm wondering...

Should I aim to do that with an individual patch for each fs, or is it
better to do a swath of them all at once in a single patch here?
