6.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: NeilBrown <neilb@xxxxxxx>
commit b372e96bd0a32729d55d27f613c8bc80708a82e1 upstream.
The page has been marked clean before writepage is called. If we don't
redirty it before postponing the write, it might never get written.
