From 7354fa4ef697191effedc2ae9a8293427708bbf5 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Thu, 12 Jan 2023 17:10:33 -0500 Subject: [PATCH] fs: dlm: be sure to call dlm_send_queue_flush() If we release a midcomms node structure, there should be nothing left inside the dlm midcomms send queue. However, sometimes this is not true because I believe some DLM_FIN message was not acked... if we run into a shutdown timeout, then we should be sure there is no pending send dlm message inside this queue when releasing midcomms node structure.
