Hi all, This is something I've wanted to see for a very long time, and it finally occurred to me that perhaps I should say something about it! It would be a very nice thing to have a flag to e2fsck, presumably -z, to zero out any unused data blocks, inodes and so on. The goal is to minimize the amount of space required after compressing a virtual disk image or similar, and to make sure any non-data isn't lying around. -hpa -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
