Changes for Linux 5.2:
- Add some extra hooks to the iomap buffered write path to enable gfs2
journalled writes.
- SPDX conversion
iomap: Add a page_prepare callback
Move the page_done callback into a separate iomap_page_ops structure and
add a page_prepare calback to be called before the next page is written
to. In gfs2, we'll want to start a transaction in page_prepare and end
it in page_done. Other filesystems that implement data journaling will
require the same kind of mechanism.
