Yes, I missed the fact that you had back pointers for blocks as well as inodes. So the block table in the tile header gets used for determing if a block is free, much like is done with FAT, right? That's a clever system; I like it. It does mean that there is a lot more metadata updates, but since you're not journaling, that should counter that effect to some extent. IMHO, it's definitely worth a try to see how well it works! - Ted - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
