OK, thanks.
Eric D's net-avoid-limits-overflow.patch switched tcp_mem and udp_mem
from proc_dointvec() to proc_doulongvec_minmax(). And
sysctl_check_table() checks `min' and `max' for
proc_doulongvec_minmax() but not for proc_dointvec().
I'm not sure which Eric to blame ;) .min and .max are optional, so
perhaps the check is wrong?
