pcpu_block_update

函数名称：pcpu_block_update_scan - update a block given a free area from a scan*@chunk: chunk of interest*@bit_off: chunk offset*@bits: size of free area* Finding the final allocation spot first goes through pcpu_find_block_fit()* to find a block that can hold the

函数原型：static void pcpu_block_update_scan(struct pcpu_chunk *chunk, int bit_off, int bits)

返回类型：void

struct pcpu_chunk *	chunk
int	bit_off
int	bits

688

s_off等于pcpu_off_to_block_off(bit_off)

689

e_off等于s_off加bits

693

如果e_off大于PCPU_BITMAP_BLOCK_BITS则返回

696

s_index等于pcpu_off_to_block_index(bit_off)

697

block等于 metadata blocks 加s_index

700

l_bit等于查找最后的CPU标志位

701

s_off等于如果s_off恒等于l_bit则0否则l_bit加1

703
