Cool, I've been meaning to update f2fs-tools in Debian, and including
these patches will allow us to generate {kvm,gce,android}-xfstests
images with this support.  I'm hoping to get to it sometime betweeen
Christmas and New Year's.

I guess there will need to be some additional work needed to create
the f2fs image with a fixed keys for a particular file system in
xfstests-bld, and then mounting and checking said image with the
appropriatre keys as well.   Is that something you've put together?

Cheers,
