Subject: [PATCH v2 1/5] kexec: make crashk_res, crashk_low_res and crash_notes symbols always visible
Date: Tue, 7 Dec 2021 00:05:10 +0800 [thread overview]
Message-ID: <20211206160514.2000-2-jszhang@kernel.org> (raw)
In-Reply-To: <20211206160514.2000-1-jszhang@kernel.org>
Make the forward declarations of crashk_res, crashk_low_res and
crash_notes always visible. Code referring to these symbols can then
just check for IS_ENABLED(CONFIG_KEXEC_CORE), instead of requiring
conditional compilation using an #ifdef, thus preparing to increase
compile coverage and simplify the code.
