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.
```
root@vm-snb-79 ~# df -h
/usr/src/linux-selftests-x86_64-rhel-7.6-7111951b8d4973bda27ff663f2cf18b663d15b48/tools/testing/selftests/openat2

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