        - Inode: Allow external list initialisation
          To allow XFS to combine the XFS and linux inodes into a single
          structure, we need to drive inode lookup from the XFS inode cache,
          not the generic inode cache. This means that we need initialise a
          struct inode from a context outside alloc_inode() as it is no longer
          used by XFS.
          After inode allocation and initialisation, we need to add the inode
          to the superblock list, the in-use list, hash it and do some
          accounting. This all needs to be done with the inode_lock held and
          there are already several places in fs/inode.c that do this list
          manipulation.  Factor out the common code, add a locking wrapper and
          export the function so ti can be called from XFS.
