torture: Remove unused definition

2014-05-14T16:46:32Z

The torture_parm() macro is the same as torture_param(), and torture_parm() is not used. This commit therefore removes torture_parm(). Signed-off-by: Pranith Kumar Signed-off-by: Paul E. McKenney Reviewed-by: Josh Triplett

torture: Check for multiple concurrent torture tests

2014-05-14T16:46:29Z

The torture tests are designed to run in isolation, but do not enforce this isolation. This commit therefore checks for concurrent torture tests, and refuses to start new tests while old tests are running. Signed-off-by: Paul E. McKenney Reviewed-by: Josh Triplett

rcutorture: Stop generic kthreads in torture_cleanup()

2014-02-23T17:04:27Z

The specific torture modules (like rcutorture) need to call torture_cleanup() in any case, so this commit makes torture_cleanup() deal with torture_shutdown_cleanup() and torture_stutter_cleanup() so that the specific modules don't have to deal with these details.

rcutorture: Abstract torture_stop_kthread()

2014-02-23T17:04:25Z

Stopping of kthreads is not RCU-specific, so this commit abstracts out torture_stop_kthread(), saving a few lines of code in the process. Signed-off-by: Paul E. McKenney Reviewed-by: Josh Triplett

rcutorture: Abstract torture_create_kthread()

2014-02-23T17:03:24Z

Creation of kthreads is not RCU-specific, so this commit abstracts out torture_create_kthread(), saving a few tens of lines of code in the process. This change requires modifying VERBOSE_TOROUT_ERRSTRING() to take a non-const string, so that _torture_create_kthread() can avoid an open-coded substitute. Signed-off-by: Paul E.

rcutorture: Fix rcutorture shutdown races

2014-02-23T17:03:21Z

Not all of the rcutorture kthreads waited for kthread_should_stop() before returning from their top-level functions, and none of them used torture_shutdown_absorb() properly. These problems can result in segfaults and hangs at shutdown time, and some recent changes perturbed timing sufficiently to make them much more probable. This commit therefore creates a torture_kthread_stopping() function that does the proper kthread shutdown dance in one centralized location. Accommodate this grouping by making VERBOSE_TOROUT_STRING() capable of taking a non-const string as its argument, which allows the new torture_kthread_stopping() to pass its "title" argument directly to the updated version of VERBOSE_TOROUT_STRING().

rcutorture: Abstract torture_shutdown()

2014-02-23T17:03:18Z

Because auto-shutdown of torture testing is not specific to RCU, this commit moves the auto-shutdown function to kernel/torture.c. Signed-off-by: Paul E. McKenney Reviewed-by: Josh Triplett

rcutorture: Abstract stutter_wait()

2014-02-23T17:02:54Z

Because stuttering the test load (stopping and restarting it) is useful for non-RCU testing, this commit moves the load-stuttering functionality to kernel/torture.c. Signed-off-by: Paul E. McKenney Reviewed-by: Josh Triplett

rcutorture: Privatize fullstop

2014-02-23T17:01:12Z

This commit introduces the torture_must_stop() function in order to keep use of the fullstop variable local to kernel/torture.c. There is also a torture_must_stop_irq() counterpart for use from RCU callbacks, timeout handlers, and the like. Signed-off-by: Paul E. McKenney Reviewed-by: Josh Triplett

rcutorture: Abstract torture_shutdown_notify()

2014-02-23T17:01:11Z

Because handling the race between rmmod and system shutdown is not specific to RCU, this commit abstracts torture_shutdown_notify(), placing this code into kernel/torture.c. This change also allows fullstop_mutex to be private to kernel/torture.c. Signed-off-by: Paul E. McKenney Reviewed-by: Josh Triplett
