The one you are adding with this patch.

Thanks -- I had noticed that you were removing extern declarations for
find_first_zero_bit() and find_next_zero_bit() and I was surprised
that this removal was not explained in the commit message, and I had
not realized that the corresponding function definitions did not exist.

I'll apply your patch and add a note in the commit message explaining
the removal.

Amicalement,
