--- Comment #3 from Tom Vijlbrief <tvijlbrief@gmail.com> ---
bufshutdown() ends with:


                if (panicstr =3D=3D NULL)=20
                        vfs_unmountall();=20
        }=20
        swapoff_all();=20

Why not just reverse the order?

So swapoff_all() before the vfs_unmountall(), so that the NFS filesystem is
still available.

Perhaps even at the start of bufshutdown().

Still wondering what the reason of a swapoff_all() call just before the act=
ual
reboot is.

--=20
