From d3001ed3a82ec2696bb13c78092d0a3460003fd7 Mon Sep 17 00:00:00 2001 From: Dongsheng Yang Date: Thu, 20 Nov 2014 21:04:56 -0500 Subject: [PATCH] btrfs: qgroup: update limit info in function btrfs_run_qgroups(). When we commit_transaction(), qgroups in btree should be updated. But, limit info is not considered currently. It will cause a problem when a qgroup of a snapshot inherit the limit info from srcqgroup, then there is an inconsistency.
