Logan Gunthorpe da573eaa3a ntb_perf: Improve thread handling to increase robustness ... This commit accomplishes a few things: 1) Properly prevent multiple sets of threads from running at once using a mutex. Lots of race issues existed with the thread_cleanup. 2) The mutex allows us to ensure that threads are finished before tearing down the device or module. 3) Don't use kthread_stop when the threads can exit by themselves, as this is counter-indicated by the kthread_create documentation. Threads now wait for kthread_stop to occur. 4) Writing to the run file now blocks until the threads are complete. The test can then be safely interrupted by a SIGINT. Also, while I was at it: 5) debugfs_run_write shouldn't return 0 in the early check cases as this could cause debugfs_run_write to loop undesirably.
