count_leading

函数名称：_leading_zeros - Count the number of zeros from the MSB back*@x: The value* Count the number of leading zeros from the MSB going towards the LSB in @x.* If the MSB of @x is set, the result is 0.

函数原型：static inline int count_leading_zeros(unsigned long x)

返回类型：int

参数：

类型	参数	名称
unsigned long	x

如果x的长度恒等于4则返回:BITS_PER_LONG减ls - find last set bit in word*@x: the word to search* This is defined in a similar way as the libc and compiler builtin* ffs, but returns the position of the most significant set bit.* fls(value) returns 0 if value is 0 or the position of the last

否则返回:BITS_PER_LONG减ls64 - find last set bit in a 64-bit word*@x: the word to search* This is defined in a similar way as the libc and compiler builtin* ffsll, but returns the position of the most significant set bit
