# Help: Debugging for CI systems and finding regressions
#
# The config is based on running daily CI for enterprise Linux distros to
# seek regressions on linux-next builds on different bare-metal and virtual
# platforms. It can be used for example,
#
# $ make ARCH=arm64 defconfig debug.config
#
# Keep alphabetically sorted inside each section.
