provide a userspace implementation.

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.

sys/vm/vm_unix.c
240–241

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.
