类型参数名称
const struct sbitmap *sb
boolset
241  weight等于0
243  以i小于@map_nr: Number of words (cachelines) being used for the bitmap.循环
244  word等于@map: Allocated bitmap.[i]
246  如果set则weight加等于bitmap_weight( & @word: word holding free bits, @depth: Number of bits being used in @word/@cleared)
248  否则weight加等于bitmap_weight( & @cleared: word holding cleared bits, @depth: Number of bits being used in @word/@cleared)
