X-Git-Tag: v4.1-rc1~30^2~15 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d3001ed3a82ec2696bb13c78092d0a3460003fd7;p=karo-tx-linux.git 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.
