From 317dd6ba6ccaa5e7c24039955c39df84072d5166 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Thu, 12 Jan 2023 17:18:45 -0500 Subject: fs: dlm: make dlm sequence id more robust When joining a new lockspace, use a random number to initialize a sequence number used in messages. This makes it easier to detect sequence number mismatches in message replies during tests that repeatedly join and leave a lockspace.
