Hi,
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.
