I suggest xin respond to messageid
20180523011821.12165-6-kent.overstreet@gmail.com> and send a NAK,
indicating that his patch seems like it will break the build, as,
looking through it, it never removes flex_array calls from the sctp
code.  If kent reposts with a conversion of the sctp code to radix
trees, we're done.  If not, you can move forward with this commit.

Ok, Xin please do that so we can more forward.

Thanks Neil.
