It's time to remove truncate_complete_page's BUG_ON(page_mapped(page)): it was there to give confidence in the new vm_truncate_count mechanism. Earlier releases had no such check, and it wouldn't be at all helpful if it ever bugged up file truncation on a production system - though we don't know of any scenario in which that could happen now.
