[Cluster-devel] [PATCH 8/9] gfs2: Fix initial quota data refcount

[Andreas Gruenbacher]

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.
