Makes sense.

+int pair_chunk_unsafe(struct chunkfile *cf,
+		      uint32_t chunk_id,
+		      const unsigned char **p)
 {
-	return read_chunk(cf, chunk_id, pair_chunk_fn, p);

+	return pair_chunk(cf, chunk_id, p, &dummy);

I have always disliked functions that require you to pass a non-NULL
pointer to some value that you may or may not want to have that function
fill out. So I was going to suggest something along the lines of
"pair_chunk() should tolerate a NULL fourth argument instead of filling
out the size unconditionally".

But that's (a) the whole point of the series ;-), and (b) unnecessary,
since this function is going to go away entirely by the end of the
series, too.

So I think that the call you made here was the right one. The rest of
the patch all looks good to me, let's read on...

Thanks,
