Merge branch 'listener-refactoring-preparations'
Eric Dumazet says:
====================
tcp: listener refactoring preparations
This patch series makes changes to TCP/DCCP stacks so that
we can switch listener code to lockless mode.
This is done by marking const the listener socket in all
appropriate paths.
FastOpen code had to be changed to not dynamically allocate
a very small structure to make code simpler for following changes.
