From 6c2545eefffc452e52302c96c955d9aa26353aa9 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Fri, 9 May 2008 16:23:17 +1000 Subject: [PATCH] module: put modversions in vermagic Don't allow a module built without versions altogether to be inserted into a kernel which expects modversions. modprobe --force will strip vermagic as well as modversions, so it won't be effected, but this will make sure that a non-CONFIG_MODVERSIONS module won't be accidentally inserted into a CONFIG_MODVERSIONS kernel.
