The behaviour of the futex operations is defined by Linux: https://man7.org/linux/man-pages/man2/futex.2.html <https://man7.org/linux/man-pages/man2/futex.2.html> Using the same error numbers helps to avoid confusion. When you look at the history of the Linux man page you see that they replaced EWOULDBLOCK with EAGAIN over time. At the time of the RTEMS futex implementation they used EWOULDBLOCK.Thanks. Just toss that in the commit. And perhaps somewhere the documentation should say this is aligned with Linux
