Subject: [PATCH tip/core/rcu 25/28] torture: Make TORTURE_TRUST_MAKE available in kvm-again.sh environment
Date: Wed,  3 Mar 2021 16:38:09 -0800	[thread overview]
Message-ID: <20210304003812.24833-25-paulmck@kernel.org> (raw)
In-Reply-To: <20210304003750.GA24696@paulmck-ThinkPad-P72>

From: "Paul E. McKenney" <paulmck@kernel.org>

Because the TORTURE_TRUST_MAKE environment variable is not recorded,
kvm-again.sh runs can result in the parse-build.sh script emitting
false-positive "BUG: TREE03 no build" messages.  These messages are
intended to complain about any lack of compiler invocations when the
--trust-make flag is not given to kvm.sh.  However, when this flag is
given to kvm.sh (and thus when TORTURE_TRUST_MAKE=y), lack of compiler
invocations is expected behavior when rebuilding from identical source
code.

This commit therefore makes kvm-test-1-run.sh record the value of the
TORTURE_TRUST_MAKE environment variable as an additional comment in the
qemu-cmd file, and also makes kvm-again.sh reconstitute that variable
from that comment.
