There are two config variables. CONFIG_HAVE_LIVEPATCH is set by those architectures for which livepatching implementation exists. CONFIG_LIVEPATCH is the actual config option turning the support in kernel on/off. What you are seeing is that if you have kernel configuration that has livepatching (CONFIG_LIVEPATCH) turned off, the sample module doesn't compile for it either. I'd say it's not unexpected behavior. -- Jiri Kosina SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe live-patching" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
