Hi, It looks like bdi_thresh will always be zero if filesystem does synchronous writepage, resulting in very poor write performance.
Hostfs (UML) is one such example, but there might be others. The only solution I can think of is to add a set_page_writeback(); end_page_writeback() pair (or some reduced variant, that only does the proportions magic). But that means auditing quite a few filesystems...
