Christoph Hellwig 0ab2a85c80 iomap: clear the per-folio dirty bits on all writeback failures ... [ Upstream commit 7ea1d9b4a8 ] write_cache_pages always clear the page dirty bit before calling into the file systems, and leaves folios with a writeback failure without the dirty bit after return. We also clear the per-block writeback bits for writeback failures unless no I/O has submitted, which will leave the folio in an inconsistent state where it doesn't have the folio dirty, but one or more per-block dirty bits. This seems to be due the place where the iomap_clear_range_dirty call was inserted into the existing not very clearly structured code when adding per-block dirty bit support and not actually intentional. Switch to always clearing the dirty on writeback failure.
