Oh, for sure.  One of the things I plan to do is to make sure that a
file system created using the *current* ext4 encryption code is
properly readable using the new fs/crypto code.  I'll also run a full
regression test run using xfstests as well.

That's one of the reasons why I wasn't going to even try to get it
done for this merge window (even if you weren't going to be closing
the merge window tomorrow).  I just didn't have the time to do a good
job, and it made sense to let the f2fs code go in first, and then
convert ext4 afterwards.
