From: zhangwei(Jovi) Date: Tue, 30 Apr 2013 22:28:53 +0000 (-0700) Subject: ARM/etm/sysrq: fix inconstistent help message of sysrq key X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=9387a393ef28b8c45dbede4fca9cd7cc56ca30ca;p=deliverable%2Flinux.git ARM/etm/sysrq: fix inconstistent help message of sysrq key Currently help message of /proc/sysrq-trigger highlights 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. This patch fix arm etm sysrq key: "etm-buffer-dump(v)" (This patch also add "-" to separate each sysrq key help word, instead of spaces) Signed-off-by: zhangwei(Jovi) Acked-by: Randy Dunlap Cc: Russell King Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- diff --git a/arch/arm/kernel/etm.c b/arch/arm/kernel/etm.c index 9b6de8c988f3..8ff0ecdc637f 100644 --- a/arch/arm/kernel/etm.c +++ b/arch/arm/kernel/etm.c @@ -254,7 +254,7 @@ static void sysrq_etm_dump(int key) static struct sysrq_key_op sysrq_etm_op = { .handler = sysrq_etm_dump, - .help_msg = "ETM buffer dump", + .help_msg = "etm-buffer-dump(v)", .action_msg = "etm", };
