It seems the code to clean up the /proc entries is using the 
proc_dir_entry directly. According to this topic, these internals 
shouldn't be used anymore:
https://stackoverflow.com/questions/38972005/proc-dir-entry-structure-linux-3-13

They still seem to be used by the 1.17.4948957 branch though, which I 
would not expect to compile either.

Did was this part to use the modern way of handling /proc already get 
rewritten in any spot from which I could copy it?

Many thanks in advance!
