From 4a20342572f66c5b20a1ee680f5ac0a13703748f Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Wed, 28 Apr 2021 21:25:58 -0700 Subject: [PATCH] nvmet: remove unsupported command noise 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.
