# 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.
