From 6ca8dfd78187d8238abc5b2996848a0c8f07948d Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 23 Jun 2016 13:34:35 +0200 Subject: [PATCH] tty: vt, convert more macros to functions Namely convert: * IS_FG -> con_is_fg * DO_UPDATE -> con_should_update * CON_IS_VISIBLE -> con_is_visible DO_UPDATE was a weird name for a yes/no answer, so the new name is con_should_update.
