base/SOURCES/0139-tests-ts_scsi_debug_init-must-not-run-in-a-subshell.patch

From 9e643d190c1c3b39423c4d00f1ddc89e2b4cc09e Mon Sep 17 00:00:00 2001
From: Ruediger Meier <ruediger.meier@ga-group.nl>
Date: Sun, 11 May 2014 08:50:28 +0200
Subject: [PATCH 139/141] tests: ts_scsi_debug_init must not run in a subshell

ts_skip and ts_die won't work from subshell. Now we simply use
TS_DEVICE which is globally set in that function.

I've made sure that we never change TS_DEVICE variable after
we've got it. So we could use it again for cleanup on exit in
ts_{finalize,die,skip} functions.
