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. Tested-by: Chandan Rajendra <[email protected]> -- chandan
