Some others to consider adding: * Check whether counter is correctly initialized from initval. * I'm not sure what kind of check you are doing in 11, but perhaps one should somewhere have a test that checks whether writing to the eventfd in the child means the child can read from the eventfd. * exceptional condition (select(exceptfds) when the counter is overflowed; and in this case read() shd return 0xffffffffffffffff. * eventfd file descriptor is preserved across execve() If you want more detail on any of the above, let me know.
