2.4 -> 2.2 differences?
With all the SCO fun going on I have people asking me what functionality we would loose if we rolled from 2.4.21 kernel to the last known stable 2.2 kernel.
Yes, weathering the lawsuit mess and all is a good plan but I'm still being asked for this information. Does anyone have a link listing what
kind of functionality would be lost, performance impact (p3 and athalon
machines), etc?

No highmem support,
No journaled filesystems.
No netfilter. Fewer networking features. Period. (ethernet bridging, etc)
Slower SMP
I don't know if it's psycological, but whenever I booted 2.2 on my desktop, it felt slower.
This was a while ago though.

You could start with Joe Pranevich's "Wonderful World of Linux 2.4" at
http://linuxtoday.com/news_story.php3?ltsn=1999-10-03-001-05-NW-LF
There have been a number of improvements and features added since but any 2.2 -> 2.4 features summary should indicate much of what you would loose in a 2.4 -> 2.2 transition.

it is easier to turn off SMP.
BTW: what will happen if there is some SMP code from IBM in the kernel which is owned by SCO? Isnt it a matter of days to remove that code? Does anybody have to pay for past usage of the code?

The core 2.2 SMP code is stuff I wrote. Caldera (aka SCO) even provided me the hardware and asked me to do it. The later table parser code is from Intel.
Too bad you don't have anything they gave you or which they took back from you that could be used against them.

Its a matter of archived public record since long ago
Yeah but likely nothing along the line of correspondence of them offering you the stuff if you give them a copy of your work on SMP which would happen to be GPL'd....

Did you open up the boxes? Perhaps there was some license note attached to the internals (`by using this machine, you declare to give up your first born etc... ')?

But would just turning off SMP shut up the lawyers? They're saying it'd take a full roll back to 2.2.
Having Gartner say not to take the suit seriously isn't helping calm down the lawyers, etc even if there is no proof.

Right now there's just a bunch of rumors and stories of people like M$ paying license fees which argumentably provides a precedent. (tactics of M$ asside, M$ isn't the topic here)

The only reason I'm still using 2.2 is that my binary of realserver won't run on 2.4.x.
