FYI, you might want to look at the high level construct we use for that
in Linux, where we pass a function pointer to format the dirent to the
VOP_READDIR equivalent. The function pointer is passed by the caller
and can format all kinds of different dirent stuctures. This hasn't
just been helpful for the 64bit ino dirent transition, but also for
foreign OS compatibility layers and in-kernel consumers like nfsd.
