From 84c0677048de1c7ddfdb10426f86485e8475f769 Mon Sep 17 00:00:00 2001 From: John Ogness Date: Mon, 30 Nov 2020 01:42:03 +0106 Subject: [PATCH 101/323] printk: relocate printk_delay() and vprintk_default() Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.215-rt107.tar.xz Move printk_delay() and vprintk_default() "as is" further up so that they can be used by new functions in an upcoming commit.
