Quoting Matt Helsley (matthltc@xxxxxxxxxx): > Add tests for plain, robust, and pi futexes. Each test sets up a > typical contended futex scenario and then awaits checkpoint.

Thanks, Matt, these now compile and run on s390. > For plain futexes we ensure that the same number of tasks that > were asleep on the futex are woken up.

(trivially fixed as bash wait returns its return value) I think you also have several places where you log a FAIL when you should probably log BROK. But I've applied this to cr_tests plus a fix for run.sh to check return values. Can you send me a fix to have plain.c log failures (unless I'm misreading and its all fine)? thanks, -serge _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
