Are label attributes really that obsecure?

I think they are.

The real problem, however, is that label attributes would just paper
over the badly thought out control flow in the function and not make the
code any better or easier to read.

So much for compromise, I thought we had agreed that at least some of the 
checks for !name, in_interrupt() or bad size values should be moved out 
from under the #ifdef CONFIG_DEBUG_VM, but this wasn't done.  This 
discussion would be irrelevent if we actually did what we talked about.
