Linux 2.5.69 extern global variables


Hi,

I am running Red Hat 7.2 and have have my sample kernel module compiled for linux 2.5.69.
when I try to insmod the kernel module, I get
"sample_module Invalid module format."
If I add __initdata in front of my global variables ( extern), this problem goes away. Can anyone help me out here? Has anyone else seen this problem?

Thanks

Taken from http://www.win.tue.nl/~aeb/linux/lk/lk-2.html#ss2.5.1 :
"
# insmod demo-module.o
Error inserting 'demo-module.o': -1 Invalid module format

The new module utilities require a module name section. Adding -DKBUILD_MODNAME=demo to the compile line suggested above solves this.
