I think there is a problem in original processing.
When add a new entry and its hash value is already exist in current 
directory, furthermore the hash value
is the last one in a leaf block, although we already found a freespace 
block for adding the new entry,
but we drop this one and continue to check, until the last same hash value.
I think the reason is that xfs_da_node_lookup_int is a common function 
for addname and lookup.


I added a condition before enter another leaf block, only when we didn't 
find a freespace block for the new entry,
then we need to enter another leaf block.
