Subject: [PATCH v18 11/17] kdump: Make parse_crashkernel_{high|low} static
Date: Wed, 22 Dec 2021 21:08:14 +0800	[thread overview]
Message-ID: <20211222130820.1754-12-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <20211222130820.1754-1-thunder.leizhen@huawei.com>

Currently, parse_crashkernel_{high|low} is only referenced by
parse_crashkernel_in_order(), and they are in the same file. So make it
static, and move it into "#ifdef CONFIG_ARCH_WANT_RESERVE_CRASH_KERNEL".
