This is a note to let you know that I've just added the patch titled fs: dlm: be sure to call dlm_send_queue_flush() to the 6.1-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: fs-dlm-be-sure-to-call-dlm_send_queue_flush.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 2360bbb166d1923d89ae2615462602af245e7ff9 Author: Alexander Aring <aahringo@xxxxxxxxxx> Date: Thu Jan 12 17:10:33 2023 -0500 fs: dlm: be sure to call dlm_send_queue_flush() [ Upstream commit 7354fa4ef697191effedc2ae9a8293427708bbf5 ] 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.
