Thanks, I did that via the attached.

Thanks, I found and fixed that earlier today 
<https://lists.gnu.org/r/bug-gnulib/2026-06/msg00072.html>.

openat2 is unusual, as it is present in GNU/Linux but not GNU/Hurd. 
That's why I listed "glibc on non-Linux" in 
doc/glibc-functions/openat2.texi. In that sense openat2 is like mseal, 
pidfd_open, epoll_create, and inotify_add_watch. I don't know of any 
other such function for which Gnulib provides a substitute.
