From fac480efcba6a9f0aea91947f151fd569538b0af Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 30 Jan 2014 17:06:30 -0800 Subject: rcutorture: Add diagnostic for unscheduled system shutdown Currently, rcutorture can terminate via rmmod, via self-shutdown, via something else shutting the system down, or of course the usual catastrophic termination. The first two get flagged, so this commit adds a message for the third. For the fourth, your warranty is void as always. Signed-off-by: Paul E.
