I'm guessing this might mean that the test bot had the DEBUG_LIST stuff enabled in its Kconfig, whereas after the rename, the default is used, which is off?
This seems a bit problematic if people had DEBUG_LIST enabled in their old kernel config and then try to reuse that config for a new kernel. I wonder whether it'd be acceptable to keep the options under their old names and let them "select" the new ones, or whether we have to choose between "keep the old bad name" and "discard people's old config flags".
