From ad86ee2b8a47590f62a4f3bc1d25dc126d121cb9 Mon Sep 17 00:00:00 2001 From: Aleksey Makarov Date: Wed, 15 Mar 2017 13:28:51 +0300 Subject: [PATCH] printk: rename selected_console -> preferred_console The variable selected_console is set in __add_preferred_console() to point to the last console parameter that was added to the console_cmdline array. Rename it to preferred_console so that the name reflects the usage. Petr Mladek: "[..] the selected_console/preferred_console value is used to keep the console first in the console_drivers list. IMHO, the main effect is that each line will first appear on this console, see call_console_drivers(). But the message will still appear also on all other enabled consoles. From this point, the name "preferred" sounds better to me. More consoles are selected (enabled) and only one is preferred (first)."
