Subject: [PATCH v2 1/6] panic: Separate sysctl logic from CONFIG_SMP
Date: Wed, 9 Nov 2022 12:00:44 -0800 [thread overview]
Message-ID: <20221109200050.3400857-1-keescook@chromium.org> (raw)
In-Reply-To: <20221109194404.gonna.558-kees@kernel.org>
In preparation for adding more sysctls directly in kernel/panic.c, split
CONFIG_SMP from the logic that adds sysctls.
