The most visible on is page migration, but there's also a write_one_page helper used by a few filesystems that would either need to get a writepage-like callback or a bigger rewrite. I agree that killing of ->writepage would be a worthwhile goal, though. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
