From 8ea0e063a78df91b1ca4d23ea8d4e2e3047f6950 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Tue, 8 Mar 2011 09:44:35 -0500 Subject: ktest: Monitor kernel while running of user tests 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.
