File kdump-clean-up-kdump-mount-points.patch of Package kdump.21347
From: Petr Tesarik <ptesarik@suse.com>
Date: Mon, 2 Sep 2019 10:01:47 +0200
Subject: Make sure that kdump mount points are cleaned up
References: bsc#1102252, bsc#1125011
Upstream: merged
Git-commit 83e48556428339668e6f23e1dccc0196a52d1b68
If the system continues to boot, kdump mount points must be
unmounted before switching to the system root. Otherwise, some
filesystems may remain mounted under the now-unavailable initrd
root, keeping the underlying devices busy during system shutdown.
