[RFC] mm: Don't use radix tree writeback tags for pages in swap cache

From: Huang Ying File pages uses a set of radix tags (DIRTY, TOWRITE, WRITEBACK) to accelerate finding the pages with the specific tag in the the radix tree during writing back an inode. But for anonymous pages in swap cache, there are no inode based writeback. So there
