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