After mpage_map_and_submit_extent() supports restarting handle if credits are insufficient during allocating blocks, it is more likely to exit the current mapping iteration and continue to process the current processing partially mapped folio again. The existing tracepoints are not sufficient to track this situation, so enhance the tracepoints to track the writeback position and the return value before and after submitting the folios.
