of them listed in opt_global.h which is not generated while building modules outside of a kernel and such modules never match real cofigured kernel. So, we should prevent our users from building obviously defective modules. Therefore, remove the root cause of the building of modules outside of a kernel - the possibility of building modules with DEBUG or KTR flags. And remove all of DEBUG printfs as it is incomplete and in threaded programms not informative, also a half of system call does not have DEBUG printf. For debuging Linux programms we have dtrace, ktr and ktrace ability. PR: 222861 Reviewed by: trasz MFC after: 2 weeks Differential Revision: https://reviews.freebsd.org/D20178
