Great to hear that you're interested in running xfstests on Android!  Probably
Ted stopped providing an arm32 root_fs because arm64 is much more common now.
It should be pretty straightforward to build an arm32 root_fs.tar yourself,
though; have you checked the documentation in
https://github.com/tytso/xfstests-bld/blob/master/Documentation/building-rootfs.md
?

It should just require:

	sudo ./setup-buildchroot --arch=armhf
	./do-all --chroot=buster-armhf --out-tar

I haven't done it in a while so I can't guarantee it hasn't gone stale, but it's
supposed to work.
