From: Keith Busch Date: Thu, 29 Apr 2021 04:25:58 +0000 (-0700) Subject: nvmet: remove unsupported command noise X-Git-Tag: v5.10.39~14 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=3851a86c3da8d5360449439fd344b0dd25ca523d;p=thirdparty%2Fkernel%2Fstable.git nvmet: remove unsupported command noise [ Upstream commit 4a20342572f66c5b20a1ee680f5ac0a13703748f ] 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.
