函数名称：Crude but fast random-number generator. Uses a linear congruential* generator, with occasional help from cpu_clock().

函数原型：unsigned long torture_random(struct torture_random_state *trsp)

返回类型：unsigned long

参数：

类型参数名称
struct torture_random_state *trsp
308  如果trs_count先自减小于0则
309  trs_state加等于local_clock()
310  trs_count等于TORTURE_RANDOM_REFRESH
312  trs_state等于trs_state乘prime 加prime
314  返回:swahw32(trs_state)

rcu_torture_writerRCU torture writer kthread. Repeatedly substitutes a new structure* for that pointed to by rcu_torture_current, freeing the old structure* after a series of grace periods (the "pipeline").
rcu_torture_fakewriterRCU torture fake writer kthread. Repeatedly calls sync, with a random* delay between calls.
rcutorture_extend_maskReturn a random protection state mask, but with at least one bit set.
rcutorture_loop_extendDo a randomly selected number of extensions of an existing RCU read-side* critical section.
rcu_torture_fwd_prog_nrCarry out need_resched()/cond_resched() forward-progress testing.
