Thanks, Mike, for explaining this better than I could. As usual, I might add! -- Brane

Re: Implement major FSFS performance related changes in the experimental FSX format

I'm not in the mood to split hairs right now (those who need to know why). I'll just say that I haven't had time to review the revprop cache branch, so obviously I can neither approve nor veto it. The general approach was discussed at the hackathon in Sheffield, and I did agree with that. Ivan, si

As you should know, current FSFS code on trunk is like this: if (log_addressing

Implement major FSFS performance related changes in the experimental FSX format

I propose to design and implement all major performance related changes of the current FSFS format in the experimental FSX format. I mean features exactly like revprop caching and log addressing. The best possible option for such features is to be implemented and released as a part of experimental
