Iterating through all the processes in a module

[Arokux B.]

Dear Greg,

thank you very much for your quick reply.

Having my code as a module I can trigger its execution (load a module)
and disable it (unload a module). How can I achieve this if the code
is inside the kernel? One possibility I see is adding an entry in the
procfs.

Regards
