Details

Summary

The vadvise syscall (aka ovadvise) is undocumented and has always been
implmented as returning EINVAL. Put the syscall under COMPAT11 and
provide a userspace implementation.

That's the plan.

Are __sys_vadvise and _vadvise symbols used by anything in the base system ? If no, then they can be removed, since we do not provide stable ABI in FreeBSD private namespace.

I believe this structure definition is useless.

  • Nothing uses _vadvise() or __sys_vadvise so don't provide them.
  • Don't document ignored struct freebsd11_vadvise_args.
