函数名称：_integrity_free - Free bio integrity payload*@bio: bio containing bip to be freed* Description: Used to free the integrity portion of a bio. Usually* called from bio_free().

函数原型：void bio_integrity_free(struct bio *bio)

返回类型：void

参数：

类型参数名称
struct bio *bio
92  bip等于bio_integrity(bio)
93  bs等于bi_pool
95  如果control flags 按位与BIP_BLOCK_INTEGRITY则释放内存
99  如果bs且mempool_initialized( & bio_integrity_pool)则
100  bvec_free( & bvec_integrity_pool, bip_vec, slab the bip came from )
102  mempool_free - return an element to the pool.*@element: pool element pointer.*@pool: pointer to the memory pool which was allocated via* mempool_create().* this function only sleeps if the free_fn() function sleeps.
103  否则
104  释放内存
107  data integrity = NULL
108  bottom bits req flags, * top bits REQ_OP. Use * accessors.与等于REQ_INTEGRITY的反
