Those old system calls are still used.
Just enable them.
statx isn't the promised land. Existing applications matter. And there
is absolutely nothing wrong with plain old 'stat' (well, we call it
"newstat" in the kernel for historical reasons) on 64-bit
architectures.
Honestly, 'statx' is disgusting. I don't understand why anybody pushes
that thing that nobody actually uses or cares about.
