Subject: [PATCH v3 1/4] initrd: Add the preprocessor guard in initrd.h
Date: Fri, 15 Jan 2021 13:46:03 +0800 [thread overview]
Message-ID: <20210115054606.124502-2-wangkefeng.wang@huawei.com> (raw)
In-Reply-To: <20210115054606.124502-1-wangkefeng.wang@huawei.com>
Add the preprocessor guard in initrd.h to prevent possible
build error from the multiple inclusion of same header file
multiple time.
