I was looking for documentation on the kstack_depth_to_print under /proc/sys/kernel, and I found it in Documentation/sysctl.txt (written by Rik).
How about /proc/sys/net? or all other directories under /sys or /proc fs?
Wouldn't it be useful to have a centralized store located in Documentation - properly structured, just a one-liner or two - on the reasons and explanations for each of these /proc or /sys parameters? And something to look for further details?
Something of the following:

Alternatively, we can write a script to extract out the partial explanations/details from existing source code, based on some coding convention/style structure, and further hand-modification from there. (given the dynamic nature of the kernel code, this may be preferred?)
I was looking for exactly this about 2 weeks ago; I needed to look up the knobs for net and disk elevators, and had to jump all over the place. I assumed that such a thing should exist, but I didn't find it. I know I would personally benefit from this, and I'm sure many others would, too.
