The various tests would all do a "wait for threads to exit" step before checking the results, but this was implemented with a simple busy wait that turns out to need careful tuning (because there was busy waiting in the threads). Rather than try to synchronize this, white box the issue (it's a low level SMP test, after all) by spinning on the thread states directly watching for the kernel to flag them dead. The downside here is that if the process fails for some reason we'll get a hang and a timeout reported from sanitycheck and not a synchronous ztest assertion. But in return, successful tests run much faster and I don't need to worry about how to tune them for IPI latency on different platforms. Signed-off-by: Andy Ross <andrew.j.ross@intel.com> |
