I am trying to create a compressed ram device

	KMOD=	md
	SRCS=	md.c
	.include <bsd.kmodule.mk>

getting this error after running make
	md.c:68:10: fatal error: ioconf.h: No such file or directory
	 #include "ioconf.h"
			  ^~~~~~~~~~
	compilation terminated.
	*** Error code 1

Cant find ioconf.h anywhere
someobe told me to follow this page
https://mail-index.netbsd.org/source-changes-hg/2020/04/07/msg169979.html
