+Subject: btrfs: add "0x" prefix for unsupported optional features
+
+From: Qu Wenruo <wqu@suse.com>
+
+commit d5321a0fa8bc49f11bea0b470800962c17d92d8f upstream.
+
+The following error message lack the "0x" obviously:
+
+  cannot mount because of unsupported optional features (4000)
+
+Add the prefix to make it less confusing. This can happen on older
+kernels that try to mount a filesystem with newer features so it makes
+sense to backport to older trees.
