PAGE_CLEAR_DIRTY and PAGE_SET_WRITEBACK are two defines used in __process_pages_contig(), to let the function know to clear page dirty bit and then set page writeback. However page writeback and dirty bits are conflicting (at least for sector size == PAGE_SIZE case), this means these two have to be always updated together. This means we can merge PAGE_CLEAR_DIRTY and PAGE_SET_WRITEBACK to PAGE_START_WRITEBACK.
