函数名称：sg_pool_init

函数原型：static __init int sg_pool_init(void)

返回类型：int

参数：无

145  以i小于SG_MEMPOOL_NR循环
146  sgp等于sg_pools加i
147  size等于size乘sizeof(structscatterlist)
149  slab等于创建高速缓存区
151  如果非slab则
152  printk(r conditions "SG_POOL: can't init sg slab %s\n", name)
154  转到:cleanup_sdb
157  pool等于mempool_create_slab_pool(SG_MEMPOOL_SIZE, slab)
159  如果非pool则
160  printk(r conditions "SG_POOL: can't init sg mempool %s\n", name)
162  转到:cleanup_sdb
166  返回:0
168  cleanup_sdb :
169  以i小于SG_MEMPOOL_NR循环
170  sgp等于sg_pools加i
172  mempool_destroy(pool)
173  删除高速缓存区
176  返回:负ENOMEM
