question about xfs/122

[Xiao Yang <yangx.jy@xxxxxxxxxxxxxx>]

Hi Darrick

When i run xfstests test case xfs/122 on RHEL7.2GA with xfsprog-dev(4.5.0),
I always get such error about xfs/122:
---------------------------------------------------------
 sizeof(struct xfs_extent_data_info) = 32
 sizeof(struct xfs_fs_eofblocks) = 128
 sizeof(struct xfs_icreate_log) = 28
-sizeof(struct xfs_refcount_key) = 4
-sizeof(struct xfs_refcount_rec) = 12
-sizeof(struct xfs_rmap_key) = 4
-sizeof(struct xfs_rmap_rec) = 24
-sizeof(struct xfs_rmapx_key) = 20
 sizeof(xfs_agf_t) = 224
 sizeof(xfs_agfl_t) = 36
 sizeof(xfs_agi_t) = 336
---------------------------------------------------------

This case can pass with modern xfsprogs(i.e. 4.3+ and all the new v5 stuff) as 
you said.
Could you tell me which specific version can support this case. In addition, 
what can be
done to work around this failure.

Please advise. Thanks very much.

Xiao Yang
