Why not to use bitmap_zero()?

...

-	memset(set->bitmap, 0xff, bitmap_size(set->num_ssid, set->num_id));
+	memset(set->bitmap, 0xff, idset_bitmap_size(set->num_ssid, set->num_id));

Why not to use bitmap_fill() ?

For this initial step, I wanted to keep changes as minimal as possible (i.e
just function renaming)

In fact, I plan to send a follow-up patch on this file.
This would remove the newly renamed idset_bitmap_size() function, use the
bitmap API directly (as you pointed-out) with
"set->num_ssid * set->num_id" as size.

It is already done this way in idset_is_empty(), so it would be more
consistent.

If the serie needs a v2 (or if required), I can add an additional 5th patch
for it. Otherwise it will send separatly later.

If you use bitmap APIs as I suggested above as the first patch, the rest will
have less unneeded churn, no?



Makes sense.

I'll wait for some other potential comments 1 day or 2 and send a v2 with the simplification you propose as an initial step.

Thanks for your feed-back.
