From bb73ae8ff394f767a8acbc99a1d682b874ba5e74 Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Thu, 24 Aug 2023 14:52:29 +0200 Subject: gfs2: Fix initial quota data refcount Fix the refcount of quota data objects created directly by gfs2_quota_init(): those are placed into the in-memory quota "database" for eventual syncing to the main quota file, but they are not actively held and should thus have an initial refcount of 0.
