This patch is a bit strange...

We see these two functions appear in pack.c

And we see parse_pack_index() came from sha1_file.c

But where did alloc_packed_git() come from?  Was the patch split
incorrectly or something?

When I applied the whole series and did

    git blame -s -w -M -C -C master.. pack.c

expecting that pretty much everything has come from sha1_file.c but
noticed that some lines were actually blamed to a version of pack.c
and these functions were among them.
