If you are going to do that, why not just add:
static vop_t **nullfs_specop_p;
static struct vnodeopv_entry_desc nullfs_specop_entries[] = {
...
};
static struct vnodeopv_desc fs_specop_opv_desc =
{ &nullfs_specop_p, nullfs_specop_entries };
VNODEOP_SET(nullfs_specop_opv_desc);
???
That way the devices get exported directly (still), but the rename,
delete, and other code can be left alone.
It's really ugly to think of a "nullfs" doing this, though, so
I guess it's sixes on which approach is used. Told you it was
crufty. 8-(.
