File kdump-add-requires-mounts-for-into-systemd-unit.patch of Package kdump

From: Petr Tesarik <ptesarik@suse.com>
Subject: Add RequiresMountsFor= line to kdump-save.service
References: bsc#936363, bsc#936475, bsc#936489
Patch-mainline: v0.8.16
Git-commit: 27a14cde287a8ddab2221e1dc5b342e5a735c7ee

If one of the required mounts times out, the systemd transaction does
not fail, and systemd may try to start kdump-save.service before the
required mounts are available. Adding all required mounts as requirement
prevents such failures.
