I just noticed that the fsck reports corruption whenever my mkfs creates a filesystem that doesn't use the whole disk. I don't test this much because I don't need it right now, and I don't even know if the official implementations accept it. But it's important to have it working for the ENOSPC tests of xfstests, which will be important once I actually start checking for ENOSPC before starting transactions. Anyway, fix this to the best of my understanding right now, though I may need to make more changes in the future once I finally get around to testing these devices on macos. Signed-off-by: Ernesto A.
