Most of the folio flag-setting functions return void. folio_start_writeback is gratuitously different; the only two filesystems that do anything with the return value emit debug messages if it's already set, and we can (and should) do that internally without bothering the filesystem to do it. This patch (of 4): There are no more callers of this wrapper.
