From 0463d04ea03a12d8a5aad42197a5945dfd78d7d6 Mon Sep 17 00:00:00 2001 From: John Ogness Date: Wed, 30 Sep 2020 11:07:34 +0206 Subject: [PATCH] printk: reduce setup_text_buf size to LOG_LINE_MAX @setup_text_buf only copies the original text messages (without any prefix or extended text). It only needs to be LOG_LINE_MAX in size.
