Documentation about sysfs/procfs entries (resent due to errors)

[Peter Teoh]

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:

|-- netfilter
|   |-- nf_conntrack_buckets:your explanation here
|   |-- nf_conntrack_checksum:your explanation here...
|   |-- nf_conntrack_count
|   |-- nf_conntrack_expect_max
|   |-- nf_conntrack_generic_timeout
|   |-- nf_conntrack_icmp_timeout
|   |-- nf_conntrack_log_invalid
|   |-- nf_conntrack_max
|   |-- nf_conntrack_tcp_be_liberal
|   |-- nf_conntrack_tcp_loose
|   |-- nf_conntrack_tcp_max_retrans
|   |-- nf_conntrack_tcp_timeout_close
|   |-- nf_conntrack_tcp_timeout_close_wait
|   |-- nf_conntrack_tcp_timeout_established
|   |-- nf_conntrack_tcp_timeout_fin_wait
|   |-- nf_conntrack_tcp_timeout_last_ack
|   |-- nf_conntrack_tcp_timeout_max_retrans
|   |-- nf_conntrack_tcp_timeout_syn_recv
|   |-- nf_conntrack_tcp_timeout_syn_sent
|   |-- nf_conntrack_tcp_timeout_time_wait
|   |-- nf_conntrack_udp_timeout
|   `-- nf_conntrack_udp_timeout_stream
|-- nf_conntrack_max
|-- token-ring
|   `-- rif_timeout
`-- unix
    `-- max_dgram_qlen


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?)
