With this patch applied, On ppc64 I get,
# blockdev --getss /dev/loop0
512
# blockdev --getpbsz /dev/loop0
512
i.e. we are back to what was being reported before commit 6c6b6f28b333
was applied.
I also executed xfstests on xfs filesystems with 4k and 32k block sizes and
did not notice any regressions.
