Subject: [PATCH] nvmet: remove unsupported command noise
Date: Wed, 28 Apr 2021 21:25:58 -0700 [thread overview]
Message-ID: <20210429042558.905404-1-kbusch@kernel.org> (raw)
Nothing can stop a host from submitting invalid commands. The target
just needs to respond with an appropriate status, but that's not a
target error. Demote invalid command messages to the debug level so
these events don't spam the kernel logs.
