I seem to remember there was some reason you wanted the folio unlocking and putting. I guess you need to drop the ref to flush it. Would it make sense for ->check_write_begin() to be passed a "struct folio **folio" rather than "struct folio *folio" and then the filesystem can clear *folio if it disposes of the page?
