Subject: [PATCH 7/8] module: add core_param_unsafe
Date: Fri, 16 Jan 2015 15:33:16 -0800 [thread overview]
Message-ID: <1421451197-19723-8-git-send-email-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <1421451197-19723-1-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.
