No defconfigs set DEBUG_INFO_COMPRESSED explicitly, but I think one issue with changing the identifier of existing kconfigs is that upon upgrading to newer kernel sources, if you run `make oldmodconfig` if you previously had DEBUG_INFO_COMPRESSED=y, kconfig doesn't know that that option has been renamed to DEBUG_INFO_COMPRESSED_ZLIB so it would be silently disabled, and image sizes would increase due to uncompressed debug info. That seems developer hostile. Masahiro, what are your thoughts on how to proceed? Should I change the pre-existing Kconfig identifier, or "let sleeping dogs lie?" -- Thanks, ~Nick Desaulniers
