BDI_WRITTEN counter is used to estimate bdi bandwidth. It must be incremented every time as bdi ends page writeback. No matter whether it was fulfilled by actual write or by discarding the request (e.g. due to shrunk i_size). Note that even before writepages patches, the case "Got truncated off completely" was handled in fuse_send_writepage() by calling fuse_writepage_finish() which updated BDI_WRITTEN unconditionally.
