From 01284764713b02be23e72338227ce536c740399a Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Tue, 12 Nov 2013 15:11:32 -0800 Subject: [PATCH] kernel/panic.c: reduce 1 byte usage for print tainted buffer sizeof("Tainted: ") already counts '\0', and after first sprintf(), 's' will start from the current string end (its' value is '\0'). So need not add additional 1 byte for maximized usage of 'buf' in print_tainted().
