Hi, Aleksa.
I met error "Operation not supported" when i ran selftests/openat2
```
# openat2 unexpectedly returned # -95 (Operation not supported) not ok 106 openat2 with valid how.mode and O_TMPFILE succeeds
```
Is there any limits to run selftests/openat2?
Some info of my testing env.
```

I believe some filesystems don't support O_TMPFILE, hence -EOPNOTSUPP. Try using a different filesystem.
