I already gave a look to reiser4, but I have some difficoultis with dancing tree structure.
But definitelly I was waiting for an extent based FS as we talked about this more than one year and a half ago, when you described me your plans for reiser in an interview on Linux&C.
Now, will have to find some time to set up a test, possibly on a 64 bit CPU.
