Subject: fs: dlm: start midcomms before scand
From: Alexander Aring <aahringo@xxxxxxxxxx>
commit aad633dc0cf90093998b1ae0ba9f19b5f1dab644 upstream.
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.
