Subject: [PATCH v7 11/12] btrfs: skip space_cache v1 setup when not using it
Date: Wed, 18 Nov 2020 15:06:26 -0800 [thread overview]
Message-ID: <4661fbae3fd777faae4ef2f50a41a2ab1842b65f.1605736355.git.boris@bur.io> (raw)
In-Reply-To: <cover.1605736355.git.boris@bur.io>
If we are not using space cache v1, we should not create the free space
object or free space inodes. This comes up when we delete the existing
free space objects/inodes when migrating to v2, only to see them get
recreated for every dirtied block group.
