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