We used to have a bug in the build system that if you did this, it would delete your whole filesystem. Some of us argued that we should leave it there just to keep people from ever doing this again :) > So, No module is getting build and again i'm not getting any Error as > well. Please tell me where i'm doing wrong. Have you built this kernel source tree before? Do a full build first, before trying to just build one directory. That should resolve the issue. And again, not as root please. greg k-h -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
