| |
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.
