bits_per_word = 1U << @shift: log2(number of bits used per word)

94

When i < @map_nr: Number of words (cachelines) being used for the bitmap. cycle See if we have deferred clears that we can batch move

97

@depth: Number of bits used in the whole bitmap. = depth

@map_nr: Number of words (cachelines) being used for the bitmap. = DIV_ROUND_UP(@depth: Number of bits used in the whole bitmap., bits_per_word)

100

When i < @map_nr: Number of words (cachelines) being used for the bitmap. cycle

101

@depth: Number of bits being used in @word/@cleared = min - return minimum of two values of the same or compatible types*@x: first value*@y: second value(depth, bits_per_word)

102

depth -= @depth: Number of bits being used in @word/@cleared
