2455 /*
2456         For better POSIX semantics from Linux client, (even better
2457         than the existing CIFS Unix Extensions) we need updated PDUs for:
2458
2459         1) PosixCreateX - to set and return the mode, inode#, device info and
2460         perhaps add a CreateDevice - to create Pipes and other special .inodes
2461         Also note POSIX open flags
2462         2) Close - to return the last write time to do cache across close
2463                 more safely
2464         3) FindFirst return unique inode number - what about resume key, two
2465         forms short (matches readdir) and full (enough info to cache inodes)
2466         4) Mkdir - set mode
2467
2468         And under consideration:
2469         5) FindClose2 (return nanosecond timestamp ??)
2470         6) Use nanosecond timestamps throughout all time fields if
2471            corresponding attribute flag is set
2472         7) sendfile - handle based copy
2473
2474         what about fixing 64 bit alignment
2475
2476         There are also various legacy SMB/CIFS requests used as is
2477
2478         From existing Lanman and NTLM dialects:
2479         --------------------------------------
2480         NEGOTIATE
2481         SESSION_SETUP_ANDX (BB which?)
2482         TREE_CONNECT_ANDX (BB which wct?)
2483         TREE_DISCONNECT (BB add volume timestamp on response)
2484         LOGOFF_ANDX
2485         DELETE (note delete open file behavior)
2486         DELETE_DIRECTORY
2487         READ_AND_X
2488         WRITE_AND_X
2489         LOCKING_AND_X (note posix lock semantics)
2490         RENAME (note rename across dirs and open file rename posix behaviors)
2491         NT_RENAME (for hardlinks) Is this good enough for all features?
2492         FIND_CLOSE2
2493         TRANSACTION2 (18 cases)
2494                 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2495                 (BB verify that never need to set allocation size)
2496                 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2497                          Unix ext?)
2498
2499         COPY (note support for copy across directories) - FUTURE, OPTIONAL
2500         setting/getting OS/2 EAs - FUTURE (BB can this handle
2501         setting Linux xattrs perfectly)         - OPTIONAL
2502         dnotify                                 - FUTURE, OPTIONAL
2503         quota                                   - FUTURE, OPTIONAL
2504
2505         Note that various requests implemented for NT interop such as
2506                 NT_TRANSACT (IOCTL) QueryReparseInfo
2507         are unneeded to servers compliant with the CIFS POSIX extensions
2508
2509         From CIFS Unix Extensions:
2510         -------------------------
2511         T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2512         T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2513         T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2514         T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC)  BB check for missing
2515                                                         inode fields
2516                                 Actually a need QUERY_FILE_UNIX_INFO
2517                                 since has inode num
2518                                 BB what about a) blksize/blkbits/blocks
2519                                                           b) i_version
2520                                                           c) i_rdev
2521                                                           d) notify mask?
2522                                                           e) generation
2523                                                           f) size_seqcount

2525         TRANS2_GET_DFS_REFERRAL               - OPTIONAL but recommended
