(I've also synchronized the upstream e2fsprogs git repo with the AOSP e2fsprogs repo as of 43f6f573dd61 and updated go/aosp-e2fsprogs-reconciliation. This commit is on the master branch, although the other AOSP commits, being bug fixes, were landed first on the maint branch and then merged into master.) - Ted
