Any reason you didn't do:

if (!commit->util)
	commit->util = xcalloc(1, sizeof(int));

xmalloc() does not initialize the memory. Therefore, it is usually 
preferred if you initialize the memory yourself. In this case, the memory 
is initialized to 0, even if it is not allocated.

It may be a minor performance issue, but it is a good habit to use xcalloc 
only if it is needed.

I think you could pretend the commit->util field to be of some
kind of int and avoid the allocation altogether ;-).
