Hi again,

as said, i'm not voting for getting the specific example patch into 
kernel source.
All i came for and would like to see is the two numbers into the 
upstream header file to avoid future namespace clashes (as said in the 
original mail).

I honestly don't know how to follow the discussion to implement this 
kind of entropy given via auxv to userland- if you (the kernel devs) 
think it makes sense the way you want it you as upstream devs can do it 
all the way you like it- i can always change it with a patch for my own 
needs in my own sources.  I can't say anything at all about all of this 
because i don't know what is important from your point of view as kernel 
maintainers and what is not.  I understand your concerns and know that 
we are talking from different perspectives, thus it is probably normal 
that our interests and technical solutions vary.

However, as said, the only thing important for me is to not use 
"arbitrary" chosen numbers for the AT_ENTROPY1 and 2 values and later 
have problems when my "private" numbers suddenly are assigned to a 
different thing by "official" kernel devs.  That would be bad for me and 
this is what i want to avoid in the first place.

So please tell me what i can do about the requirements and the time and 
what the usual process is for asking how to get the numbers into the 
kernel so i can start using them for my own work.

Thanks in advance,


Alex
