[PATCH v2 net-next 0/5] tcp: listener refactor part 16

A CONFIG_PROVE_RCU=y build revealed an RCU splat I had to fix.

I added const qualifiers to various md5 methods, as I expect
to call them on behalf of request sock traffic even if
the listener socket is not locked. This seems ok, but adding
const makes the contract clearer. Note a good reduction
of code size thanks to request/establish sockets convergence.

Eric Dumazet (5):
tcp: md5: fix rcu lockdep splat
tcp: use C99 initializers in new_state[]
tcp: md5: input path is run under rcu protected sections
tcp: md5: remove request sock argument of calc_md5_hash()
tcp: md5: get rid of tcp_v[46]_reqsk_md5_lookup()
