I know that we need to get off our duffs starting to make progress on the FS front. My FreeBSD time is right now tied up on making the swapon/swapoff stuff real. There is action about to happen on the Jeffery Hsu Lite-2 stuff, and I heard that Kirk's ordered-delay writes project might be starting. This weekend I am going to dedicate a day or so to work with people to understand all of this so that I can help contribute. DG needs to get involved also, and I think that his time is freeing up (that damn -stable release has tied up very very valuable resources.) My language (composition) skills suck, but I have excellent reading skills. Reading Terry's stuff is sometimes very difficult :-). Makes me think that I have 2nd grade reading skills at times... I have convinced myself that he is right about the managment of the namei buffers, but there is MUCH MUCH more to do!!! Some people have been commenting (in private and -core email) that we are moving too fast... We on some fronts we are moving like molasses, and I sure would like to see more progress. I am kind of the VM person (Well DG and I are), but do not feel nearly as competent on the FS front. As an ABSOLUTE minimum, I can provide alot of "nice" hooks into the VM system for filesystem memory management (LFS really needs help, for example.) I really see the need for a fairly close, collabarative effort on the FS code structure and filesystems. However, there are, at times, diverging opinions on how things should be done. We need to get organized!!! I am at my physical limit now, working a regular job, needing to find another SO or pseudo-SO, and of course my most important SO needs attention (The FreeBSD issues that I already have committed to.) I don't know if this position is acceptable to all, but I am thinking that we need to (eventually) empower an FS development team, like we have kind of done so with the VM stuff. Sorry for my rambling, John
