block_size

函数名称：Size is a power-of-two in the range 512..PAGE_SIZE,* and the case we care about most is PAGE_SIZE.* So this *could* possibly be written with those* constraints in mind (relevant mostly if some* architecture has a slow bit-scan instruction)

函数原型：static inline int block_size_bits(unsigned int blocksize)

返回类型：int

参数：

类型	参数	名称
unsigned int	blocksize

1667

返回:log2 - log base 2 of 32-bit or a 64-bit unsigned value*@n: parameter* constant-capable log of base 2 calculation* - this can be used to initialise global variables from constant data, hence* the massive ternary operator construction* selects the (blocksize)
