%async_delalloc_pages and %nr_async_submits are used to indicate that compressed writeback actually starts its work, but since we have already used double filemap_flush() alike, we don't need those two any more. %nr_async_bios was used to show congestion for writeback, but a later change adopts bdi_write_congested() to do the same job, it's not needed, either.
