These changes are not yet part of an official Android release (as they showed up after the 'N' release) but you'll see that e2fsprogs has been updated to 1.43 release and in the contrib/android directory, there is a new e2fsdroid program. That was some great work done by Adrien Schildknecht as part of his Google intern project, and he consulted with me on the design of how to refactor that functionality out of make_ext4fs. There are still some changes needed before we can completely get rid of make_ext4fs (it is called programmatically from the volume manager, and that last bit of work hasn't been converted yet). And of course there has still be some polishing and bug fixing that has been happening to make sure things are smooth on Mac and Windows build hosts, etc. So as usual with the AOSP master branch, understand that it is a work in progress, and it hasn't gotten the same level of testing as an official android "letter" release.
