Hm, I guess if anybody would be capable of _really_ fixing vm in upto-pre10 state, he would have done it already. It's not that people would not have tried, but it looks like nobody is able to get the _whole_ picture of this. Surely there are people that know a lot about certain parts of the (old) vm code, and thats exactly what leads to this Linus' statements here sounding like "I had a look at part xyz of it and it's a mess. Patch appended." (see pre10 vm patch). You have to keep in mind that a lot of people on the planet try to use 2.4 in a unbelievably broad variety of setups - and quite a number of them relies on released kernels. If you take a close look at 2.4.7, 2.4.8, 2.4.9 you may well find out, that they're unusable compared to 2.2.19. You cannot go on like this. I really do back Andrea and Linus for this step, because I can _see_ a great win in performance _and_ things got less complex in this code. So there is a much bigger chance to tilt the last remaining problems in short time (hopefully before 2.4.10 or .11). So I guess the right thing to do now is give Andrea good input of leftover, reproducible problems to give him a chance to fix them. A major discussion about "doing it all the way round" makes only sense, if someone comes up with something _at least_ as good as Andrea's code. Then its "Lonely Linus"' decision to choose. Whatever he will choose, a good percentage LKML will be against it. This is a normal thing, the guy that has to make the decision is alone most of the time. The only way for you to find out if he is right is to _try_ it. If he is, tell him. If he isn't, send a patch. He couldn't have been that wrong the last years, though.

Just _one_ opinion from an unimportant guy,
