Now for this patch. I noticed this issue when I was doing negative testing
from userspace via prctl and the return value didn't match what was in
the pcrtl man page.
Ahh, that's the bit of background I was looking for. Thanks for that,
and thanks for the patch!
Hey Dave, just to clarify, is there anything else here I need to do for an ack, or can I consider this staged?
I also sent out the prctl changes this am, so you can see more of the context.
