fls

函数名称：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

函数原型：static __always_inline int fls(unsigned int x)

返回类型：int

div64_u64_rem	div64_u64_rem - unsigned 64bit divide with 64bit divisor and remainder@dividend: 64bit dividend@divisor: 64bit divisor@remainder: 64bit remainder This implementation is a comparable to algorithm used by div64_u64
div64_u64	div64_u64 - unsigned 64bit divide with 64bit divisor@dividend: 64bit dividend@divisor: 64bit divisor* This implementation is a modified version of the algorithm proposed* by the book 'Hacker's Delight'. The original source and full proof

__ilog2_u32	-constant log of base 2 calculators* - the arch may override these in asm/bitops.h if they can be implemented* more efficiently than using fls() and fls64()* - the arch is not required to handle n==0 if implementing the fallback
get_order	get_order - Determine the allocation order of a memory size@size: The size for which to get the order Determine the allocation order of a particular sized block of memory
task_state_index
count_leading_zeros	_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.
