From 7da0c611579b722ac649cd5bc4a0e8151f70e9ee Mon Sep 17 00:00:00 2001 From: Tiwei Bie Date: Fri, 11 Oct 2024 12:04:36 +0800 Subject: [PATCH] um: Do not propagate dtb parameter to kernel This parameter is UML specific and is unknown to kernel. It should not be propagated to kernel, otherwise it will be passed to user space as an environment option by kernel with a warning like: Unknown kernel command line parameters "dtb=/foo", will be passed to user space.
