Subject: allow individual core dump methods to be unlimited when sending to a pipe (fix 2)
From: Neil Horman <nhorman@xxxxxxxxxxxxx>
Heres the subsequent patch that I promised you. It changes all the limit
passing to be unsigned longs. I've built it on x86, x86_64 and ia64 and it
seems to be good to go. It leaves off the bit that you have above, since
you've already included that.
