After checking out a6f38f9b4a92dd43d78415796c034b54237049a1, it works. But after 29a32a7d9a00b06e7141fe0311926b651ff92b1b, the issue start appearing

Oh I forget to rename the PROCNAME. After doing that it works fine. Thanks!

Please, use ascii a-z for the name, not numbers then try again

no issues from the building I see, show your dmesg when loading the module. remember you need to kill to activate the proc entry, after loading the module.
