VERBOSE_TOROUT_STRING("torture_shuffle task started")

410

循环

411

We can use __set_current_state() here because schedule_timeout() calls* schedule() unconditionally.

412

Shuffle tasks such that we allow shuffle_idle_cpu to become idle.* A special case is when shuffle_idle_cpu = -1, in which case we allow* the tasks to run on all CPUs.

413

Absorb kthreads into a kernel function that won't return, so that* they won't ever access module text or data again.

414

当非Is it time for the current torture test to stop?循环

415

Each kthread must wait for kthread_should_stop() before returning from* its top-level function, otherwise segfaults ensue
