Subject: [PATCH 7/8] module: add core_param_unsafe
Date: Mon, 30 Mar 2015 16:20:09 -0700	[thread overview]
Message-ID: <1427757610-27882-8-git-send-email-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <1427757610-27882-1-git-send-email-dmitry.torokhov@gmail.com>

Similarly to module_param_unsafe(), add the helper to be used by core
code wishing to expose unsafe debugging or testing parameters that taint
the kernel when set.
