Subject: [PATCH 1/2] device-mapper: use dynamic debug instead of compile-time config option
Date: Thu, 14 May 2020 08:09:28 +0200	[thread overview]
Message-ID: <20200514060929.85469-2-hare@suse.de> (raw)
In-Reply-To: <20200514060929.85469-1-hare@suse.de>

Switch to use dynamic debug to avoid having recompile the kernel
just to enable debugging messages.
