openmosix breaking /proc module

Hi,

I'm trying to get this simple /proc module taken from the Linux Kernel Module Programming guide, to compile, but it gives me the following error in a file related to openmosix

/lib/modules/2.4.26-om1/build/include/hpc/hpctask.h:103: error: storage size of `features' isn't known
proc.c:196: error: storage size of `File_Ops_4_Our_Proc_File' isn't known
proc.c:226: error: storage size of `Inode_Ops_4_Our_Proc_File' isn't known
proc.c:249: error: storage size of `Our_Proc_File' isn't known
make: *** [proc.o] Error 1


The kernel module is as follows

How do I get this to compile on openmosix?
Is there any sample openmosix module which writes to /proc, which I look at?
