# Regression script will vary LBA formats from 0 to n which are defined by
# the format.*.xml files. These files use combinations of LBA data sizes:
# {512, 1024, 2048 and 4096} and meta data sizes: {0, 8, 64, 128}.
# The script needs the format.*.xml files. When you run
# ./regression.sh <user param> it invokes ./runtnvme -f <format.*.xml>
# to format namespace. For each iteration namespace #1 is formatted
# with the LBA and MS settings from the corresponding xml file.
# Once the namespace is formatted, the regression script invokes
# ./runtnvme <user param> to run entire compliance suite or part of it as
# specified in the parmaters.
# If any failure is detected either when formatting the namespace or when
# a test throws an expection, the script immediately stops for user to
# investigate.
