That's exactly where I came form with my extent list work. Although the rbtree performance was horrible due to the memory overhead and I've switched to a modified b+tree at the moment.. > OTOH, if we're going to have to dynamically allocate the memory for > the extent/inline data for the data fork, it may just be easier to > make the entire data fork a dynamic allocation (like the attr fork). I though about this a bit, but it turned out that we basically always need the data anyway, so I don't think it's going to buy us much unless we shrink the inode enough so that they better fit into a page. -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
