torture: Add config2csv.sh script to compare torture scenarios
This commit adds a config2csv.sh script that converts the specified torture-test scenarios' Kconfig options and kernel-boot parameters to .csv format. This allows easier comparison of scenarios when one fails and another does not. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

# Create a spreadsheet from torture-test Kconfig options and kernel boot
|

# parameters. Run this in the directory containing the scenario files.

#
|

# Usage: config2csv path.csv [ "scenario1 scenario2 ..." ]
|
||||
#
|
||||
# By default, this script will take the list of scenarios from the CFLIST
|
||||
# file in that directory, otherwise it will consider only the scenarios
|
||||
# specified on the command line. It will examine each scenario's file
|
||||
# and also its .boot file, if present, and create a column in the .csv
|
||||
# output file. Note that "CFLIST" is a synonym for all the scenarios in the
|
||||
# CFLIST file, which allows easy comparison of those scenarios with selected
|
||||
# scenarios such as BUSTED that are normally omitted from CFLIST files.
