Great work, its nice to see none, or fewer No help availables in the kernel 
configuration.
Some quick glances:

Linux Kernel v2.4.5-ac5 Configuration
CML1

Bottom of IDE, ATA and ATAPI Block devices;

< > Support Promise software RAID (NEW)   -> Help
There is no help available for this kernel option.

The Help for '[ ]   IGNORE word93 Validation BITS' isn't much help either, 
although I safely say N and move on.

Between SCSI and IEEE 1394;
Fusion MPT device support  --->     doesn't lead anywhere.

How about
"Say "Y" or "M" if you have a Promise Fasttrak (tm) Raid controller
and want linux to use the softwarraid feature of this card.
This driver uses /dev/ataraid/dXpY (X and Y numbers) as device names.

If you have a Promise Fasttrak(tm) card but do not use the BIOS provided
raid feature, say "N".

Um, tell me what the symbol name and prompt for this is, please?

Configure.help is complete

[Eric S. Raymond]

It gives me great pleasure to announce that the Configure.help master
file is now complete with respect to 2.4.5.  Every single one of the
2699 configuration symbols actually used in the 2.4.5 codebase's C
source files or Makefiles now has an entry in Configure.help.

This does not, of course, mean the job of maintaining Configure.help
is done; symbols will be added and dropped in the future (there are a
handful of new ones in ac5, all now documented), and some existing
entries could stand to be rewritten and expanded.  But we have passed
a milestone -- maintainance will now be a matter of keeping the boat
bailed rather than trying to ignore a hole in the side. 

Thanks to all the contributors who helped put together the over 550 
entries necessary to catch up, too many to name here.  The result
is available at:

	http://www.tuxedo.org/~esr/cml2/Configure.help.gz

Though carried on the CML2 project page, it can be used with CML1 and
is current with respect to both Linus's tree and Alan's.

I now have two requests of Linus and Alan:

1. Please pick up this work now.  It is a really substantial improvement
   on what you have in your trees, incorporating it cannot break anything,
   and you'll help prevent unnecessary hassles due to clashing patches
   in the future.

2. Please make a policy of rejecting patches that add new configuration 
   symbols without also adding an explanatory Configure.help entry --
   and please *announce* that you will do so.  We can raise our standards
   now, and for the sake of having a well-documentated kernel and
   configuration system I submit that we ought to.

Would it be great to have a similar documentation for those hundreds of
"files" under /proc ?. Something like:

/proc/sys/dev/raid/speed_limit_min

Subsystem: RAID
Module:    md.o
Configuration Option: Multi-device support (RAID and LVM) -> Multiple
devices driver support (RAID and LVM) -> RAID support
Type: positive integer ¿32-bit? long
Units: kilobytes per second
Related ioctls: /proc/sys/dev/raid/speed_limit_max

Short description: minumun guaranteed array reconstruction speed (in KB/s).

Description: minimun guaranteed array reconstruction speed for RAID-0, 
RAID-5 and the ones derived from them. When the array is reconstructing, 
this parameter sets the minimun reconstruction speed of the array, 
borrowing I/O time from applications if needed. Don't set this parameter 
too high or your system will be very little responsive when the array is
reconstructing (give applications I/O some room :).

Is this something reasonable to ?.

Regards.

I'm not skilled enough to write even simple C or PERL programs, but maybe
I could try improving linux kernel documentation. Not sure about the
procedure to take nor the available time I'll have. But I'm willing to
help where I can.

Would be nice to know whether there is some sense in documenting the whole
/proc, just the part of ot that will stay in 2.5.x or continue with what
we have rught now.

I'll check the mentioned program to see if there is the information I
need. Stay tuned :)

Regards.

Powertweak has descriptions for most of the usable /proc entries,
in XML format but the descriptions are easily extractable. Maybe it's 
a good idea to make the powertweak set complete instead / share the set

We should start removing the crap from procfs in 2.5. Documenting shit is
a good step, but taking it out would be better.

What's wrong with procfs? 

It allows a general interface to the kernel that does not require new
syscalls/ioctls and can be accessed from user space without specifically
compiled programs. You can use shell scripts, java, command line etc.

Imho, a procfs should be for process-information, nothing else.
The procfs in its current form, while useful, is something horrible
that should be taken out on the backyard and shot using slugs.

Ehrmmm. No, but seriously, the non-process stuff should be separate
from the procfs. Maybe call it kernfs or whatever.

Yes, and it's also totally non standardised.

It clearly fills a need, though, and has the distinct side benefit of 
cutting down on the proliferation of ioctls. Sure, it's non-standard 
and a mess. But it's semi-documented, easy to use, and v. general. 
What's the preferred alternative, to state the first question another 
way? For any single small project/driver, creating a new fs simply 
isn't going to happen.

If I understand Al Viro correctly we'll get per driver filesystems
in 2.5 (based on ramfs) which you can union-mount on /proc
(possibly using autofs) to get the current /proc tree.

Happy Hacking.
