Subject: [PATCH 3/5] crash: rename crash_core to vmcore_info
Date: Fri,  5 Jan 2024 18:33:03 +0800
Message-ID: <20240105103305.557273-4-bhe@redhat.com>
In-Reply-To: <20240105103305.557273-1-bhe@redhat.com>
References: <20240105103305.557273-1-bhe@redhat.com>
Precedence: bulk
MIME-Version: 1.0
Content-type: text/plain
Content-Transfer-Encoding: 8bit

Now only vmcoreinfo handling related code is in crash_core.c, so do the
renaming as follows:
 kernel/{crash_core.c => vmcore_info.c}
 arch/xxx/kernel/{crash_core.c => vmcore_info.c}
 include/linux/{crash_core.h => vmcore_info.h}
 CONFIG_CRASH_CORE   => CONFIG_VMCORE_INFO

And also update the old ifdeffery of CONFIG_CRASH_CORE, including of
<linux/vmcore_info.h> and config item dependency on CRASH_CORE
accordingly.
