Version 1.61
------------
Fix append problem to Samba servers (files opened with O_APPEND could
have duplicated data). Fix oops in cifs_lookup. Workaround problem
mounting to OS/400 Netserve. Fix oops in cifs_get_tcp_session.
Disable use of server inode numbers when server only
partially supports them (e.g. for one server querying inode numbers on
FindFirst fails but QPathInfo queries works).
Version 1.60
-------------
Fix memory leak in reconnect. Fix oops in DFS mount error path.
