Subject: sysrq: more explicit, less terse help messages
From: Randy Dunlap <randy.dunlap@xxxxxxxxxx>
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.
