In the OPU path, f2fs_submit_page_write() sets fio->submitted to 1. However, in the IPU path, fio->submitted is never set and remains zero. As a result, successful IPU writes are not accounted for. This can cause asynchronous writeback to continue beyond its budget. Set fio->submitted in f2fs_inplace_write_data() after a page is successfully merged into a bio or submitted, so that successful IPU writes are included in the writeback accounting.
