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

Hi all,
I use the kernel version "3.10.0-4" that came with Ubuntu distribution.
When I compile the example module I got from LKMPG (hello-5.c) and try to load the driver by passing the module with the following command, it gives the following error:
# insmod parameter.ko mystring="bebop"
Error: could not insert module parameter.ko: Unknown symbol in module
Error in dmesg:
[ 3687.132110] parameter: Unknown parameter `mystring'
However, if I insert the module without any parameters, it gets inserted just fine.
# insmod parameter.ko
I am attaching the source code for reference. Kindly let me know what could be done.
Thanks,
Binoy
