The reason: Linus is an idiot. Ok, I don't really think so, but he started with the name calling; he should go over to OpenBSD (or better: create his own *BSD) and become another Theo de Raadt ;-). Honestly, what he's doing is factless rants against a discussion that's definitely fact-based. Larger pages help to keep a large memory organized without too many TLB misses. Larger blocks help to keep a large disk with high transfer rates and low seek capability fast. The fact that Linux has big problems with large pages and blocks means probably it's doing it completely wrong. The fact that people discuss this, and write code, even though Linus shouts against them is encouraging. The big flamefest this generates is discouraging. If this also results in a veto from Linus once the code is ready, even worse. Then I think it's time to fork Linux.
