bitmap_set

Name:bitmap_set

Proto:static __always_inline void bitmap_set(unsigned long *map, unsigned int start, unsigned int nbits)

Type:void

Parameter:

Type	Parameter	Name
unsigned long *	map
unsigned int	start
unsigned int	nbits

398

If __builtin_constant_p(nbits) && nbits == 1 Then __set_bit - Set a bit in memory*@nr: the bit to set*@addr: the address to start counting from* Unlike set_bit(), this function is non-atomic. If it is called on the same* region of memory concurrently, the effect may be that only one operation* succeeds.

400

Else if __builtin_constant_p(start & BITMAP_MEM_MASK) && IS_ALIGNED(start, BITMAP_MEM_ALIGNMENT) && __builtin_constant_p(nbits & BITMAP_MEM_MASK) && IS_ALIGNED(nbits, BITMAP_MEM_ALIGNMENT) Then memset((char * )map + start / 8, 0xff, nbits / 8)

405

Else __bitmap_set(map, start, nbits)
