From 989152e113bfcb4fbfbad6f3aed6f43be4455919 Mon Sep 17 00:00:00 2001
From: Kazuhito Hagio <k-hagio-ab@nec.com>
Date: Tue, 25 Feb 2020 16:04:55 -0500
Subject: [PATCH] Introduce --check-params option
Currently it's difficult to check whether a makedumpfile command-line
is valid or not without an actual panic. This is inefficient and if
a wrong configuration is not tested, you will miss the vmcore when an
actual panic occurs.
In order for kdump facilities like kexec-tools to be able to check
the specified command-line parameters in advance, introduce the
--check-params option that only checks them and exits immediately.

Subject: [PATCH] makedumpfile: Remove duplicated variable declarations
When building on Fedora 32, following error is observed:

multiple definition of `splitting_info_t'; elf_info.o:/builddir/build/BUILD/kexec-tools-2.0.20/makedumpfile-1.6.7/makedumpfile.h:1265: first defined here
And apparently, these variables are wrongly declared multiple times. So
remove duplicated declaration.
