From 643f5cfa610f475c7465e4158b2b1fdd170fac10 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Tue, 1 Aug 2023 14:09:44 -0400 Subject: fs: dlm: cleanup lock order This patch cleanups the lock order to hold at first the close_lock and then held the nodes_srcu read lock. Probably it will never be a problem as nodes_srcu is only a read lock preventing the node pointer getting freed.
