Subject[PATCH 8/9] ktest: Monitor kernel while running of user tests
From: Steven Rostedt <srostedt@redhat.com>

Record the console of tests to both the console and the log.
Also, record the bug reports afte the test has completed.
Currently, if a kernel bug happens while running the userland
test, the test stops and will not record the kernel bug. This
makes it difficult to solve what happened.
