Add an __iomap_put_folio() helper to encapsulate unlocking the folio, calling ->page_done(), and putting the folio. Use the new helper in iomap_write_begin() and iomap_write_end(). This effectively doesn't change the way the code works, but prepares for successive improvements. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com> Reviewed-by: Darrick J.
