The existing RAID code does not support hot swapping, IIRC. This means that, if you had a hardware problem which RAID is supposed to correct, you have to take the machine down in order to replace the failed disk. It is a valid argument, IMHO, that the existing RAID code should not even be considered "production." So, upgrading the code "for nothing" is a misnomer. Since no sane administrator would use RAID in a production environment without upgrading it I don't see the logic in holding back the patches.
I >THOUGH< that was one of the so-called benefits of Linux -- that you don't have to wait a long time for some monolithic company or organization to make new features and bug fixes available to you. Failure to upgrade a more-heavily-tested and "stable" RAID base in the 2.2 kernel directly contradicts this belief.
Needless to say, I'm not a happy camper. I guess I won't be until almost a year past when 2.2 came out when the new RAID code is integrated into the kernel (my prediction, hopefully too pessimistic). Unfortunately there's not a whole lot about it that I can do as it seems Alan, Linus, and Ingo all agree that it's not going into 2.2...
