And I'm telling you, it's wrong. Traditional Unix is dead, and it's dead exactly _because_ it prioritized those kinds of loads. I'm perfectly happy to take specialized workloads into account, but it needs to help the _normal_ case too. Somebody mentioned 4k CPU support as an example, and that's a good example. The only reason we support 4k CPU's is that the code was made clean enough to work with them and actually help clean up the SMP code in general. I've also seen Andrea talk about how it's all rock solid. We _know_ that is wrong, because the anon_vma bug is not solved. That bug apparently happens under low-memory situations, so clearly nobody has really stressed the low-memory case. So here's the deal: make the code cleaner, and it's fine. And stop trying to sell it with _crap_.
