From 42bfba9eaa33dd4af0b50b87508062a41ec26653 Mon Sep 17 00:00:00 2001 From: Ursula Braun Date: Thu, 14 Nov 2019 13:02:41 +0100 Subject: net/smc: immediate termination for SMCD link groups SMCD link group termination is called when peer signals its shutdown of its corresponding link group. For regular shutdowns no connections exist anymore. For abnormal shutdowns connections must be killed and their DMBs must be unregistered immediately. That means the SMCR method to delay the link group freeing several seconds does not fit. This patch adds immediate termination of a link group and its SMCD connections and makes sure all SMCD link group related cleanup steps are finished.
