From 208b95ce3afbc2f4ef0a84b8cfdd7a8b94d17a5a Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Tue, 6 Jan 2009 14:41:13 -0800 Subject: [PATCH] sysrq: more explicit, less terse help messages Eliminate sysrq terse help mode; make sysrq help messages more meaningful (more explicit/verbose). Make the sysrq action letter clearer by listing it explicitly in more sysrq help messages (when it is not simple/clear). The SysRq help message now looks like this: SysRq : HELP : loglevel(0-9) reBoot terminate-all-tasks(E) memory-full-oom-kill(F) kill-all-tasks(I) saK show-backtrace-all-active-cpus(L) show-memory-usage(M) nice-all-RT-tasks(N) powerOff show-registers(P) show-all-timers(Q) unRaw Sync show-task-states(T) Unmount show-blocked-tasks(W) Addresses http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=330403.
