From e9fb365a8847dfe8a9fccae0dce77abf7276b5da Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 30 Mar 2016 11:20:48 -0700 Subject: [PATCH] rcutorture: Dump trace buffer upon shutdown When running from the scripts, rcutorture is completely headless, so there is no way to to manually dump the trace buffer. This commit therefore unconditionally dumps the trace buffer upon timed shutdown. However, if you are using rmmod to end the test, it is still up to you to manually dump the trace buffer.
