From f345650964936395307d9d6bdee0168cf7d926e7 Mon Sep 17 00:00:00 2001 From: "zhangwei(Jovi)" Date: Tue, 30 Apr 2013 15:28:51 -0700 Subject: [PATCH] kgdb/sysrq: fix inconstistent help message of sysrq key Currently help message of /proc/sysrq-trigger highlight its upper-case characters, like below: SysRq : HELP : loglevel(0-9) reBoot Crash terminate-all-tasks(E) memory-full-oom-kill(F) kill-all-tasks(I) ... this would confuse user trigger sysrq by upper-case character, which is inconsistent with the real lower-case character registed key. This inconsistent help message will also lead more confused when 26 upper-case letters put into use in future.
