I agree with the idea of standardizing the /proc filesystem. However,
I would like this to go further than just reformatting the current output.
All drivers should report statistics in a standard way. Let me give you
an example:

To obtain IO statistics about two different brand SCSI controllers, I
would have to write two different parsers - one for each /proc entry. Not
to mention the fact that /proc entries for some controllers don't even
report IO statistics.

Basically the current situation is that drivers report what they want -
any way they want to report it. This prevents us from writing any sort
of STANDARD analysis tools - something crutial to system tuning.

My vote is for standardizing CONTENT as well as format.
