+ for (p = list, i = 0; i < cnt; i++, p = p->next) {
Here "i" can reach "cnt - 1" at most, so ...
+ if (i == cnt) {
+ /* clean-up unused elements if any */
+ free_commit_list(p->next);
+ p->next = NULL;
+ }
... "i == cnt" is always false above. I think it should be "i == cnt - 1".
And with your code one can wonder why the cleanup is part of the loop.

Could you send it inline as explained in Documentation/SubmittingPatches?
Thanks,
