[PATCH 0/3] selftests/mm: revert pthread_barrier change and

From: Edward Liaw

On Android arm, pthread_create followed by a fork caused a deadlock in
the case where the fork required work to be completed by the created
thread.

The previous patches incorrectly assumed that the parent would
always initialize the pthread_barrier for the child thread. This
reverts the change and replaces the fix for wp-fork-with-event with the
original use of atomic_bool.
