f2fs inode is so large, small files can be stored directly in the inode, rather than just storing a single block address and storing the data elsewhere.
This RFC patch set is just to enable f2fs support inline data: files less than about 3.6K can be stored directly in inode block. TODO: make small dirs inline too.
