update_refs(): fix constness
The old signature of update_refs() required a (const struct ref_update **) for its updates_orig argument. The "const" is presumably there to promise that the function will not modify the contents of the structures. But this declaration does not permit the function to be called with a (struct ref_update **), which is perfectly legitimate. C's type system is not powerful enough to express what we'd like. So remove the first "const" from the declaration. On the other hand, the function *can* promise not to modify the pointers within the array that is passed to it without inconveniencing its callers. So add a "const" that has that effect, making the final declaration (struct ref_update * const *). Signed-off-by: Michael Haggerty <> Signed-off-by: Junio C Hamano <>
