Which no current included fs supports. And parallel file systems btw get
exciting for everyone once you have virtualisation.

Hans can learn to work with people, most folks in wheelchairs cannot
take lessons and walk. Many of them have tried months of physiotherapy.
to learn to walk again. I think your comparison is insulting to a lot of
the disabled.

Linus refused ext3 initially. It went in because it had a userbase,
vendors shipping it and reliable clean code. Saying "no" a lot is really
rather important to keeping the kernel maintainable. I regularly meet
cases we should have said "no" a lot louder 8)

It doesn't matter if reiser4 causes crashes. It matters that people can
fix them, that they are actively fixed and the code is maintainable. It
will have bugs, all complex code has bugs. Hans team have demonstrated
the ability to fix some of those bugs fast, but we also all remember
what happened with reiser3 later on despite early fast fixing.

One big reason we jump up and down so much about the coding style is
that its the one thing that ensures someone else can maintain and fix
code that the author has abandoned, doesn't have time to fix or that
needs access to specific hardware the authors may not have.
