[PATCH 1/2] Btrfs: don't call btrfs_qgroup_free if just btrfs_qgroup_reserve fails
From: Wang Shilong <wangsl-fnst@cn.fujitsu.com>
commit eb6b88d92c6df083dd09a8c471011e3788dfd7c6 leads into another bug.
If it is just because qgroup_reserve fails, the function btrfs_qgroup_free
should not be called, otherwise, it will cause the wrong quota accounting.

[PATCH v0 00/18] btfs: Subvolume Quota Groups
This is a first draft of a subvolume quota implementation. It is possible
to limit subvolumes and any group of subvolumes and also to track the amount
of space that will get freed when deleting snapshots.
The current version is functionally incomplete, with the main missing feature
being the initial scan and rescan of an existing filesystem.
I put some effort into writing an introduction into
