Message-ID: <5136C106.40308@huawei.com> Date: Wed, 6 Mar 2013 12:07:34 +0800 From: "zhangwei(Jovi)" <jovi.zhangwei@...wei.com> To: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org>, Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH] sysrq: allow user trigger sysrq by upper-case character key See the help text output of /proc/sysrq-trigger: SysRq : HELP : loglevel(0-9) reBoot Crash terminate-all-tasks(E) memory-full-oom-kill(F) kill-all-tasks(I) ... Most command is referenced by responding upper-case character, this would hint user can trigger sysrq by upper-case character key, but that's wrong, sysrq only accept lower-case character currently. It's reasonable to let user trigger sysrq by upper-case character key.
