Hi I have written a KLD module that implements a syscall I wrote this module on 3.2-release, although this module is going to be used on a 3.0-release machine The relevant support for writing a syscall module was added after 3.0-release and is present in 3.1-release according to http://www.FreeBSD.org/cgi/cvsweb.cgi/src/sys/sys/sysent.h.diff?r1=1.19&r2=1.20 Is it possible for me to hack my kernel module to work on freebsd 3.0-release? I have tried patching the sys/sysent.h file with the patch linked above and the module compiles perfectly, although when I kldload'd the module the system crashed and rebooted. I didnt see the crash message, although I can get that if it will help. So my question is, is it possible for me to hack my kernel module to work on FreeBSD 3.0-release? If not, can isolated patches be made to the kernel short of doing a cvsup for src-all to enable this to work?
