So, maybe adding an "official" 'bitmap_size()' (which is already existing and duplicated in a few places) would ease things.
It would replace the 'nr_minors = BITS_TO_LONGS(end) * BITS_PER_LONG;' and hide the implementation details of the bitmap API.
Something like:
static __always_inline size_t bitmap_size(unsigned long nr_bits)
{
return BITS_TO_LONGS(nr_bits) * sizeof(long);
}
Yes, I think this would be a useful helper. Should be sizeof(unsigned long) though to keep things consistent.
