Subject: [PATCH v5 10/10] btrfs: skip space_cache v1 setup when not using it
Date: Tue, 27 Oct 2020 14:08:04 -0700 [thread overview]
Message-ID: <09febed7882924087141f081273fb4bbcaae7928.1603828718.git.boris@bur.io> (raw)
In-Reply-To: <cover.1603828718.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.
