Can we leave it zero by default? I affraid this patch won't get much
testing before 4.11-REL. The super specialized users will always be
able to set net.inet.ip.portrange.randomized whatever they want to.
The next thing I am worry about - some users already have
net.inet.ip.portrange.randomized=1 in their /etc/sysctl.conf and now
we are going to change a meaning of this sysctl. Can we garantee
there are no any side effects with this setting?
I failed to find the documentation part of your patch also :-)
