Subject: tcp: add queue_add_hash to tcp_request_sock_ops
X-Git-Tag: v4.14-rc1~7092^2~253^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=695da14eb0af21129187ed3810e329b21262e45f;p=platform%2Fkernel%2Flinux-rpi.git

tcp: add queue_add_hash to tcp_request_sock_ops

Add queue_add_hash member to tcp_request_sock_ops so that we can later
unify tcp_v4_conn_request and tcp_v6_conn_request.
