module_param does not work in Ubuntu 13.10 - Kernel 3.10.0-4

[sanmukh rao]

I have kernel 3.11.0-rc7 and it seems to be working fine. Are you sure the
file attached is the correct one or there is no typo? See the output which
I got compiling your file and loading it as a module in the attachment.

Thanks,
Sanmukh
