| # Test out: |
| # pv#979606: xfs bug in going from attr2 back to attr1 |
| # |
| # Test bug in going from attr2 back to attr1 where xfs |
| # (due to xfs_attr_shortform_bytesfit) |
| # would reset the di_forkoff to the m_offset instead of |
| # leaving the di_forkoff alone as was intended. |
| # |
| # We create enough dirents to push us past m_attroffset, |
| # and create an EA so we have a fork offset |
| # and then turn on attr1 and add one more EA which |
| # will write over the shortform dirents. |
