From 9dce29e65b38591eac0ce6786bdb725aea1eadeb Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (VMware)" Date: Wed, 1 Jul 2020 09:28:39 -0400 Subject: ktest.pl: Have config-bisect save each config used in the bisect When performing a automatic config bisect via ktest.pl, it is very useful to have a copy of each of the bisects used. This way, if a bisect were to go wrong, it is possible to retrace the steps and continue at the location before the error was made. The ktest.pl will make a copy of the good and bad configs, labeled as such, as well as a number attached to it that represents the iteration of the bisect. These files are saved in the ktest temp directory where it currently stores the good and bad config files.
