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() |
Name | Describe |

torture_lock_busted_write_delay | |
torture_spin_lock_write_delay | |
torture_rwlock_write_delay | |
torture_rwlock_read_delay | |
torture_mutex_delay | |
torture_rwsem_write_delay | |
torture_rwsem_read_delay | |
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. |
