Tao Ma	f19d5870cb	ext4: add normal write support for inline data ... For a normal write case (not journalled write, not delayed allocation), we write to the inline if the file is small and convert it to an extent based file when the write is larger than the max inline size.

Tao Ma	67cf5b09a4	ext4: add the basic function for inline data support ... Implement inline data with xattr. Now we use "system.data" to store xattr, and the xattr will be extended if the i_size is increased while we don't release the space during truncate.
