From c4d1d11f3b669847b261eacab123fe8b98a91d13 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Wed, 23 Apr 2014 22:04:56 -0400 Subject: ktest: Put back in the CONFIG_BISECT_CHECK The new rewrite left out the CONFIG_BISECT_CHECK, which allows the user to test that their "bad" config still is bad and their "good" config still is good. This is especially important as the configs are passed through a "make oldconfig" to update them with the lastest kernel. Things could change that causes a bad config to work, or a good config to break. The check is done after the configs have run through the oldconfig processing.
