This looks correct to me. Unfortunately the kernel's definitions for the stat
family are inconsistent in a lot of different ways, and the naming between
fstat and newfstatat is just one more instance of this. In theory, the 'new'
macros refer to the kernel's "struct stat", while the non-prefixed ones
refer to the syscalls taking "struct __kernel_old_stat".

Comparing the riscv64 file to the aarch64 version shows that the aarch64
version matches what the kernel defines, no idea why the riscv64 version
is different.
