Ok, but be aware that you won't be able to take code from the Linux kernel and place it in a file marked with that license header (because the code authors haven't given permission for it to be placed under any other license other than GPLv2.) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
