NAK - please use /sys/module/module/parameters/sig_enforce.
And I would rather keep this parameter bool_enable_only, plain and simple. What use case do you have/why would you want to disable signature enforcement - after having enabled it - during runtime? None of this is explained nor justified in the cover letter.
