The original patch that made this a CONFIG option is then much better as we avoid forcing new and untested behaviour on the users. We all know that compressing the modules are simple. And unless someone comes up with *very* good arguments then we should just use gzip with default parameters. If we go for the "keep the .ko extension but compress" then someone needs to answer the obvious questions: - will this break on a typical distribution - will this break busybox users Sam -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
