...fairly rough state, meaning it won't warn you if you try to format a mounted device, or warn you if the cluster size you choose is so small that bitmap operations are unbearably slow, so just be careful. The only upcoming on-disk change that we forsee at this point is to do a last pass of le##_to_cpu/cpu_to_le## macros around everything in user and kernel. As of this release, we actually seem to work on 2.4 and 2.6, little and big endian, 32- and 64-bit, and hard sector sizes from 512 to 4096. :) For any of you interested enough to know the details of what changed, we will be coming up with...
