Oops. Sorry, I made a mistake, you should check out the code from the 
source forge cvs to have the latest version of the code using sysfs. The 
 0.4 still uses the dev/char.  Remark that with dev/char it'll work for 
you but you better use sysfs instead and then check out the latest 
version of the code.

This is a legacy issue, the first version of the code was using 
sys_security hook. Afterwards, when we switched to char/dev and the hook 
was removed we didn't change the name of the function but keep calling 
that function internally. Please remark that the code corresponding to 
registering this hook has been commented, though I should tell that we 
should have removed that code in order to avoid any confusion.

Sorry again,
Makan
