torture_random

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

Proto:unsigned long torture_random(struct torture_random_state *trsp)

Type:unsigned long

Parameter:

Type	Parameter	Name
struct torture_random_state *	trsp

308

If --trs_count < 0 Then

309

trs_state += local_clock()

310

trs_count = TORTURE_RANDOM_REFRESH

312

trs_state = trs_state * prime + prime

314

Return swahw32(trs_state)

lock_torture_writer	Lock torture writer kthread. Repeatedly acquires and releases* the lock, checking for duplicate acquisitions.
lock_torture_reader	Lock torture reader kthread. Repeatedly acquires and releases* the reader lock.
rcu_read_delay
srcu_read_delay
rcu_torture_writer	RCU 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_fakewriter	RCU torture fake writer kthread. Repeatedly calls sync, with a random* delay between calls.
rcutorture_extend_mask	Return a random protection state mask, but with at least one bit set.
rcutorture_loop_extend	Do a randomly selected number of extensions of an existing RCU read-side* critical section.
rcu_torture_fwd_prog_nr	Carry out need_resched()/cond_resched() forward-progress testing.
