Hi Pankaj,

So I tested this on Linux 6.6 on Power8 qemu (which I had it handy).
xfs/558 passed with both 64k blocksize & with 4k blocksize on a 64k
pagesize system.
However, since on this system the quota was v4.05, it does not support
bigtime feature hence could not run xfs/161. 

xfs/161       [not run] quota: bigtime support not detected
xfs/558 7s ...  21s

I will collect this info on a different system with latest kernel and
will update for xfs/161 too.
