I'll change it to FREE_AND_NULL and submit my patch as-is, my reading
of the rest of this thread is that making it a function instead of a
macro would be interesting, but has its own caveats that are likely
better considered as part of its own series, whereas this just changes
existing code to its macro-expanded functional equivalent.

Here's v3 with that change. Nothing but the macro name (and comments,
commit messages etc. referring to it) have changed.

Ævar Arnfjörð Bjarmason (2):
  git-compat-util: add a FREE_AND_NULL() wrapper around free(ptr); ptr =
    NULL
  *.[ch] refactoring: make use of the FREE_AND_NULL() macro

Thanks.

Perhaps somebody wants to do a follow-up patch on top of these two
patches to add .cocci rule e.g.

	@@
	type T;
	T *ptr;
	@@
	- free(ptr);
	- ptr = NULL;
	+ FREE_AND_NULL(ptr);

so that we can periodically sweep new candidates, to which this
macro can be applied?
