From fcef0e6c27ce109d2c617aa12f0bfd9f7ff47d38 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Wed, 2 Jun 2021 09:45:15 -0400 Subject: [PATCH] fs: dlm: fix lowcomms_start error case This patch fixes the error path handling in lowcomms_start(). We need to cleanup some static allocated data structure and cleanup possible workqueue if these have started.
