Re: [PATCH] selftests/nolibc: libc-test: avoid -Wstringop-overflow warnings

Hi Thomas,

Newer versions of glibc annotate the poll() function with __attribute__(access) which triggers a compiler warning inside the testcase poll_fault. Avoid this by using a plain NULL which is enough for the testcase. To avoid potential future warnings also adapt the other EFAULT testcases, except select_fault as NULL is a valid value for its argument.

Looks good to me. I wouldn't be surprised if we're soon forced to do the same with select() on some archs where it might be emulated.

Feel free to push it to the shared repo.

Thanks! Willy
