https://man7.org/linux/man-pages/man2/epoll_wait.2.html says epoll_wait2 was added in linux 5.11.

Linux 5.10 was a major LTS release from a few years ago that is still supported; it's possible that the build bot is running an old kernel version that doesn't yet support this header.

If you can ssh into the build bot that this is failing on, please grab the output from `cat /proc/version` to confirm this theory.
