it is not yet available and will only work with future kernels. In
addition to that - isn't the move of stuff like that into the vfs layer
done to be able to switch between different implementations (for example
generic posix acls and nfs4 acls ...). With the same argument I would
like to be able to let users decide which preallocation method to use:
the XFS ioctl or the future generic one.
