This will allow us to move the generic readlink logic into the VFS and get
rid of the readlink method.
If inode has i_link set then this patch changes behavior, because
generic_readlink will return the cached contents instead of calling
i_op->get_link. It would be hard to imagine that this change could break
userspace in any sane setup, though.
