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.
