类型参数名称
struct rnd_state *state
63  s1等于prandom_u32_state - seeded pseudo-random number generator.*@state: pointer to state structure holding seeded state.* This is used for pseudo-randomness with no outside seeding.* For more random results, use prandom_u32().(s1, 6U, 13U, 4294967294U, 18U)
64  s2等于prandom_u32_state - seeded pseudo-random number generator.*@state: pointer to state structure holding seeded state.* This is used for pseudo-randomness with no outside seeding.* For more random results, use prandom_u32().(s2, 2U, 27U, 4294967288U, 2U)
65  s3等于prandom_u32_state - seeded pseudo-random number generator.*@state: pointer to state structure holding seeded state.* This is used for pseudo-randomness with no outside seeding.* For more random results, use prandom_u32().(s3, 13U, 21U, 4294967280U, 7U)
66  s4等于prandom_u32_state - seeded pseudo-random number generator.*@state: pointer to state structure holding seeded state.* This is used for pseudo-randomness with no outside seeding.* For more random results, use prandom_u32().(s4, 3U, 12U, 4294967168U, 13U)
