Subject: [PATCH 3/4] KASan: only print to stderr
Date: Mon, 11 Sep 2023 14:56:18 +0200	[thread overview]
Message-ID: <> (raw)
In-Reply-To: <>

Part of KASan output, like the stack trace, is already printed to
stderr, while some others are printed to stdout. Let's print everything
to stderr as not to complicate debugging when stdout and stderr go to
different consoles.
