函数名称：bio_put_slab

函数原型：static void bio_put_slab(struct bio_set *bs)

返回类型：void

参数：

类型参数名称
struct bio_set *bs
120  struct bio_slab * bslab = NULL
123  mutex_lock( & bio_slab_lock)
125  以i小于bio_slab_nr循环
126  如果bio_slab恒等于slab则
127  bslab等于bio_slabs[i]
128  退出
132  如果WARN(!bslab, r conditions "bio: unable to find slab!\n")则转到:out
135  WARN_ON(!slab_ref)
137  如果slab_ref先自减则转到:out
140  删除高速缓存区
141  slab = NULL
143  out :
