+
+	<para>This VFS module is part of the

+
+	<para>
+		The <command>vfs_btrfs</command> VFS module exposes Btrfs
+		specific features for use by Samba.
+	</para>
+
+	<para>
+		Btrfs allows for multiple files to share the same on-disk data
+		through the use cloned ranges. When an SMB client issues a
+		request to copy duplicate data (via FSCTL_SRV_COPYCHUNK), this
+		module maps the request to a Btrfs clone range IOCTL, instead
+		of performing reads and writes required by a traditional copy.
+		Doing so saves storage capacity and greatly reduces disk IO.
+	</para>
+
+	<para>
+		This module is stackable.
