Thanks for your patch!  A few nitpicks below:

> Subject: [PATCH] Removed unnecessary void* from hashmap.h that caused compile warnings

From Documentation/SubmittingPatches:

    Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
    instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy
    to do frotz", as if you are giving orders to the codebase to change
    its behavior.

I liked the subject Philip suggested in the other thread: "hashmap.h:
remove unnecessary void*", or maybe "hashmap.h: remove unnecessary
variable".

As above, this should be described in an imperative mood, and describe
why this is a good change and should be merged.  Maybe something along
the lines of the below?

    In 'hashmap_enable_item_counting()', item is assigned but never
    used.  This causes a warning on HP NonStop.  As the variable is
    never used, fix this by just removing it.

I like it. Do you need this resubmitted? Or should I just learn for next
time?

Cheers,
Randall

I think it would be good if you resubmit the patch.  These rules tend
to be applied quite strictly, as you can also see when looking at the
git commit history.  So with the updated commit message Junio should
just be able to pick it up (unless there's something I missed here as
well :))

As a side note, I just noticed the two submissions both had [PATCH] in
the title, whereas new submissions should be marked as such using
[PATCH v2] etc. as prefix, so it's easier for reviewers to know which
version is the newer one.

I'll queue the attached for today's iteration.  Thanks, both.

Subject: [PATCH] hashmap.h: remove unused variable

In 'hashmap_enable_item_counting()', item is assigned but never
used.  This causes a warning on HP NonStop.  As the variable is
never used, fix this by just removing it.
