函数名称：Generate some initially weak seeding values to allow* to start the prandom_u32() engine.

函数原型：static int __init prandom_init(void)

返回类型：int

参数：无

202  prandom_state_selftest()
204  遍历可用CPU(i)
205  state等于per_cpu(net_rand_state, i)
206  weak_seed等于i加jiffies按位异或The random_get_entropy() function is used by the /dev/random driver* in order to extract entropy via the relative unpredictability of* when an interrupt takes places versus a high speed, fine-grained* timing source or cycle counter()
208  prandom_seed_early(state, weak_seed, true)
209  prandom_warmup(state)
212  返回:0
