2532/*
2533        For better POSIX semantics from Linux client, (even better
2534        than the existing CIFS Unix Extensions) we need updated PDUs for:
2535
2536        1) PosixCreateX - to set and return the mode, inode#, device info and
2537        perhaps add a CreateDevice - to create Pipes and other special .inodes
2538        Also note POSIX open flags
2539        2) Close - to return the last write time to do cache across close
2540                more safely
2541        3) FindFirst return unique inode number - what about resume key, two
2542        forms short (matches readdir) and full (enough info to cache inodes)
2543        4) Mkdir - set mode
2544
2545        And under consideration:
2546        5) FindClose2 (return nanosecond timestamp ??)
2547        6) Use nanosecond timestamps throughout all time fields if
2548           corresponding attribute flag is set
2549        7) sendfile - handle based copy
2550
2551        what about fixing 64 bit alignment
2552
2553        There are also various legacy SMB/CIFS requests used as is
2554
2555        From existing Lanman and NTLM dialects:
2556        --------------------------------------
2557        NEGOTIATE
2558        SESSION_SETUP_ANDX (BB which?)
2559        TREE_CONNECT_ANDX (BB which wct?)
2560        TREE_DISCONNECT (BB add volume timestamp on response)
2561        LOGOFF_ANDX
2562        DELETE (note delete open file behavior)
2563        DELETE_DIRECTORY
2564        READ_AND_X
2565        WRITE_AND_X
2566        LOCKING_AND_X (note posix lock semantics)
2567        RENAME (note rename across dirs and open file rename posix behaviors)
2568        NT_RENAME (for hardlinks) Is this good enough for all features?
2569        FIND_CLOSE2
2570        TRANSACTION2 (18 cases)
2571                SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2572                (BB verify that never need to set allocation size)
2573                SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2574                         Unix ext?)
2575
2576        COPY (note support for copy across directories) - FUTURE, OPTIONAL
2577        setting/getting OS/2 EAs - FUTURE (BB can this handle
2578        setting Linux xattrs perfectly)         - OPTIONAL
2579        dnotify                                 - FUTURE, OPTIONAL
2580        quota                                   - FUTURE, OPTIONAL
2581
2582        Note that various requests implemented for NT interop such as
2583                NT_TRANSACT (IOCTL) QueryReparseInfo
2584        are unneeded to servers compliant with the CIFS POSIX extensions
2585
2586        From CIFS Unix Extensions:
2587        -------------------------
2588        T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2589        T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2590        T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2591        T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC)  BB check for missing
2592                                                        inode fields
2593                                Actually a need QUERY_FILE_UNIX_INFO
2594                                since has inode num
2595                                BB what about a) blksize/blkbits/blocks
2596                                                          b) i_version
2597                                                          c) i_rdev
2598                                                          d) notify mask?
2599                                                          e) generation
2600                                                          f) size_seqcount
2601        T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2602        TRANS2_GET_DFS_REFERRAL               - OPTIONAL but recommended
