Subject: [PATCH v2 1/8] crash_core.c: remove unnecessary parameter of function
Date: Tue, 29 Aug 2023 20:16:03 +0800 [thread overview]
Message-ID: <20230829121610.138107-2-bhe@redhat.com> (raw)
In-Reply-To: <20230829121610.138107-1-bhe@redhat.com>
In all call sites of __parse_crashkernel(), the parameter 'name' is
hardcoded as "crashkernel=". So remove the unnecessary parameter 'name',
add local varibale 'name' inside __parse_crashkernel() instead.
