Hello Omar, I have executed xfstests on a big endian ppc64 guest with 'MOUNT_OPTIONS="-o space_cache=v2"' config option. I have also executed generic/127 on a filesystem created using "fragment-free-space-tree.py" that you had provided sometime ago. I did not notice any regressions during the test runs.
