Subject: kasan inline + CONFIG_DEBUG_TEST_DRIVER_REMOVE kernel panic
Date: Mon, 10 Oct 2016 11:37:27 -0400 (EDT) [thread overview]
Message-ID: <1219480016.67057.1476113847440.JavaMail.zimbra@redhat.com> (raw)
In-Reply-To: <907882571.66590.1476113724660.JavaMail.zimbra@redhat.com>
Not sure if anyone reported this before. With this kernel config, it is 100% kernel panic so far with today's
mainline master HEAD.
