类型参数名称
mempool_t *pool
struct bio_vec *bv
unsigned intidx
154  如果非idx则返回
156  idx自减
158  BIO_BUG_ON(idx >= We support 6 different bvec pools, the last one is magic in that it* is backed by a mempool.)
160  如果idx恒等于BVEC_POOL_MAX则
161  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.
162  否则
163  bvs等于bvec_slabs加idx
165  kmem_cache_free(slab, bv)
