what do you mean? i'm not doing it like that.
i defined a function:

int
isallowed(File *f)
{
	if(f->cp == cons.chan)
		return 1;
	switch(allowed){
	case 0:
		return 0;
	case -1:
		return 1;
	default:
		return f->uid == allowed;
	}
}

which is used both in iaccess() (see last line)
and 9p1.c and 9p2.c to handle wstat. i didnt
want to spread this godmode logic all over the
place but have just *one* place for it. you
see, this function also handles direct commands
from the console (f->cp == cons.chan) and
"allow all" (allow == -1) (for backwards compatibility
with the uid-less "allow" console command).
