+Subject: [PATCH] btrfs: Use default subvolume as filesystem root
+
+BTRFS volume consists of a number of subvolumes which can be mounted separately
+from each other. The top-level subvolume always exists even if no subvolumes
+were created manually. A subvolume can be denoted as the default subvolume i.e.
+the subvolume which is mounted by default.
+
+The default "default subvolume" is the top-level one, but this is far from the
+common practices used in the wild. For instance, openSUSE provides an OS
+snapshot/rollback feature based on BTRFS. To achieve this, the actual OS root
+filesystem is located into a separate subvolume which is "default" but not
+"top-level". That means that the /boot/dtb/ directory is also located inside
+this default subvolume instead of top-level one.
+
+However, the existing btrfs u-boot driver always uses the top-level subvolume
+as the filesystem root. This behaviour 1) is inconsistent with
+
+    mount /dev/sda1 /target
+
+command, which mount the default subvolume 2) leads to the issues when
+/boot/dtb cannot be found properly (see the reference).
+
+This patch uses the default subvolume as the filesystem root to overcome
+mentioned issues.
