+Subject: [PATCH] lightnvm: disable the subsystem
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In commit 9ea9b9c48387 ("remove the lightnvm subsystem") the lightnvm
+subsystem was removed as there is no hardware in the wild for it, and
+the code is known to have problems.  This should also be disabled for
+older LTS kernels as well to prevent anyone from accidentally using it.
