It's customers that are doing this. I think some of them are using their own tools. Others are probably using whatever comes on their distro.

They should probably upgrade their tools, be they from the distro or 
their own (It was my understanding that /proc/stat was depricated and 
going to be removed in the not-to-distant future).

As I said in my mail, it's a customer driven issue. As long as customers rely on /proc/stat we'll keep trying. You can't tell a customer how he/she should be doing things on their systems.

I doubt you have many customers using 2.4.28.... I suspect that by now
the majority of people is either using an (ancient) 2.4 vendor kernel or
a 2.6 kernel. The very low number of reports on lkml about 2.4 seems to
confirm that ...

"25% of accidents are caused by drunken drivers. That means
75% of accidents are caused by drivers which did not drink.
So why keep people complaining about alcohol and driving?"

Is that what you mean? You must be kidding!

The majority of _our_ customers are using 2.4.x kernels
(x beeing in the range from 19 to 28pre3) and it looks like
it will stay that for quite a while...

I second this. The only one of our customers who tried 2.6 went back to
2.4 because of poor network performance, scheduling problems and stability
issues.

Very true. You just have to read any 2.6 changelog to understand that
it *is* a development kernel ! The difference between 2.5 and 2.6 is
that the test platform now is larger and includes production systems.

Obviously no one is using 2.4.28 yet, but it's pretty hard to update the ancient kernels. I've also submitted patches to our partners to fix this in their distros.

You must be kidding, aren't you ? I would better say that the very high
number of reports on lkml about 2.6 seems to confirm that 2.6 still is
a toy !

Marcelo has done a great job at getting 2.4 stable, and now people are
installing it in remote locations or embedded system with no planned
updated at all. And it works. Just like people did with 2.0 recently.
This may be why there are so few reports.

Mike, 

I dont like the patch either.

If you can have the same statistics through /proc/partitions 
(do I get this right?) just tell that to users.

patch so cciss stats are collected in /proc/stat

[mike.miller]

Currently cciss statistics are not collected in /proc/stat. This patch
bumps DK_MAX_MAJOR to 111 to fix that. This has been a common complaint
by customers wishing to gather info about cciss devices.
Please consider this for inclusion. Applies to 2.4.28-pre3.

Thanks,
mikem

This patch has been reject about half a million times, why are people
submitting it again and again?

You get more detailed statistics in /proc/partitions.

The answer to this is to use the latest sysstat tools.  the latest 
version of iostat, sar, etc draw information out of /proc/partitions 
rather than out of /proc/stat.  Or are you using some other home rolled 
tool in this case?
