Edward Liaw 7a233d8959 selftests/mm: fix ARM related issue with fork after pthread_create ... commit 8c864371b2 upstream. Following issue was observed while running the uffd-unit-tests selftest on ARM devices. On x86_64 no issues were detected: pthread_create followed by fork caused deadlock in certain cases wherein fork required some work to be completed by the created thread. Used synchronization to ensure that created thread's start function has started before invoking fork.
