Hi, I am doing some research about how SSD can better cooperate with XFS. So I need to know much about the design of the XFS. I find some material in new xfs wiki, but I would like to know more about internal design and details in old xfs wiki. It's a pity that the old one can not work now. I'd like to know if the web will recover and if there is a way to get the material. Best Regards Taylor
