From aad633dc0cf90093998b1ae0ba9f19b5f1dab644 Mon Sep 17 00:00:00 2001 From: Alexander Aring aahringo@redhat.com Date: Thu, 12 Jan 2023 17:10:31 -0500 Subject: [PATCH] fs: dlm: start midcomms before scand
The scand kthread can send dlm messages out, especially dlm remove messages to free memory for unused rsb on other nodes. To send out dlm messages, midcomms must be initialized. This patch moves the midcomms start before scand is started.
