返回类型：void

参数：

类型参数名称
struct sbitmap *sb
unsigned intdepth
91  bits_per_word等于1U左移@shift: log2(number of bits used per word)位
94  以i小于@map_nr: Number of words (cachelines) being used for the bitmap.循环See if we have deferred clears that we can batch move
97  @depth: Number of bits used in the whole bitmap.等于depth
98  @map_nr: Number of words (cachelines) being used for the bitmap.等于DIV_ROUND_UP(@depth: Number of bits used in the whole bitmap., bits_per_word)
100  以i小于@map_nr: Number of words (cachelines) being used for the bitmap.循环
101  @depth: Number of bits being used in @word/@cleared等于两数取小(depth, bits_per_word)
102  depth减等于@depth: Number of bits being used in @word/@cleared
