From 8191792c18c55ee444588100cf0464bd8c0bf5f3 Mon Sep 17 00:00:00 2001 From: Kuniyuki Iwashima Date: Tue, 19 Dec 2023 09:18:33 +0900 Subject: tcp: Remove dead code and fields for bhash2. Now all sockets including TIME_WAIT are linked to bhash2 using sock_common.skc_bind_node. We no longer use inet_bind2_bucket.deathrow, sock.sk_bind2_node, and inet_timewait_sock.tw_bind2_node.
