I had some questions while reviewing that patch, and after closer inspection I think I found what I think are some problems, and in order to work through them I came up with this patch series to lay out what I think the problems are and my attempt at addressing them. The series has been rearranged a bit since I put it together. Patch 3 includes some background and terminology that might be more useful at the beginning, but I'm leaving it as-is for now. The more I look at the end result of the series the more confident I am that it's correct. However I still need some convincing--either to point out where I've got something wrong, or to affirm that what I have is right. -Alex _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
