Subject: [PATCH V3 net-next 0/3] TCP experimental option for SMC rendezvous

Dave,

SMC-capability is to be negotiated with a TCP experimental option.
As requested during code review of our previous approach using
netfilter hooks, here's a new version. It touches tcp-code in the
first patch and exploits the new tcp flag in the smc-code.

Kind regards, Ursula

Changelog:

V3:
* move include for linux/unaligned/access_ok.h to tcp_input.c

V2:
* switch to current jump labels API
* remove static key checking in smc_set_capability()
  (comment from Eric Dumazet)
* use inet_request_sock parameter for smc_set_option_cond()
* smc_listen_work(): replace local variable lgr_lock_taken by new labels
                     and separate this change into a prerequisite first
                     patch

Ursula Braun (3):
  smc: fix mutex unlocks during link group creation
  tcp: TCP experimental option for SMC
  smc: add SMC rendezvous protocol
