Subject: Re: [PATCH net-next 0/7] sctp: network namespace support Part 2: per net tunables


Since I am motivated to get things done, and since there has been much
grumbling about my patches not implementing tunables, I have added
tunable support on top of my last patchset.

I have performed basic testing on the these patches and nothing
appears amis.

The sm statemachine is a major tease as it has all of these association
and endpoint pointers in the common set of function parameters that turn
out to be NULL at the most inconvinient times.  So I added to the common
parameter list a struct net pointer, that is never NULL.
