My point is that no code gets into the kernel without having a
significant amount of exposure first. This means exposure to other
developers, and exposure to users. Why do you think reiser4 is different
from other projects in this regard? It definitely is not.

I can sort-of agree with that. Fixing file systems bugs is like fixing
driver bugs, a freeze doesn't stop that in any way.

Sure yes, I'd like to see the code. If for nothing else than to give it
a test spin on a rainy day. And I'm curious about several things.

Sorry I don't agree. reiser4 _may_ get it when it has proved itself
ready.
