File kdump-run-mkinitrd-if-fadump-is-active.patch of Package kdump.21349

From: Petr Tesarik <ptesarik@suse.com>
Date: Fri, 20 Apr 2018 17:54:19 +0200
Subject: Run mkinitrd if fadump is active
References: bsc#1089917
Upstream: merged
Git-commit: a25562cb0ff7d2b6d6df2dded8bd29c2e4d7e9ea

With fadump, the default initrd is used. It is better to call the
normal mkinitrd script to achieve consistent behaviour between
updates triggered by kdump and other changes that may require a
rebuild of the initrd.
