/proc/meminfo for 2.0, 2.2 & 2.4.x

[Mike Fedyk <mfedyk@matchmail.com>]

Hi everyone.

I'm working on a script that parses /proc/meminfo for output to rrd-tool.

It's part of lrrd-client, and currently it parses the Mem: and Swap: lines
for its information, and if they're not there, it goes through rest of the
file to parse the output.  I'm thinking of reversing that parsing, or
eliminating the Mem: and Swap: line parsing completely (the information is
available lower in the file).

I'm planning on supporting 2.4 (stock, rmap and aa VM), as well as 2.6
kernels, but I don't run 2.0 or 2.2 kernels anymore.

Instead of booting a bunch of old kernels, maybe you guys could post the
output of /proc/meminfo to the list.

I'm interested in:
 o 2.0 and any variations (fond memories :)
 o 2.2 and any variations (haven't booted this in a while)
 o 2.4 with rik's origional VM (similair to rmap, but don't have any examples)
 o 2.4 with -aa VM (should be same as stock)
 o 2.4 with rmap VM (adds some fields for active, and inactive lists)
 o 2.4 with stock VM (no VM patches!)
 o 2.4 and any variations (if there's anything else in 2.4 that modifies
                           /proc/meminfo!!!)
 o 2.6 and any variations

Let the posting begin! :)

Here's what I get on a 2.4.20-rmap15e kernel:
