1903         For better POSIX semantics from Linux client, (even better
1904         than the existing CIFS Unix Extensions) we need updated PDUs for:
1905
1906         1) PosixCreateX - to set and return the mode, inode#, device info and
1907         perhaps add a CreateDevice - to create Pipes and other special .inodes
1908         Also note POSIX open flags
1909         2) Close - to return the last write time to do cache across close more safely
1910         3) PosixQFSInfo - to return statfs info
1911         4) FindFirst return unique inode number - what about resume key, two forms short (matches readdir) and full (enough info to cache inodes)
1912         5) Mkdir - set mode
1913
1914         And under consideration:
1915         6) FindClose2 (return nanosecond timestamp ??)
1916         7) Use nanosecond timestamps throughout all time fields if
1917            corresponding attribute flag is set
1918         8) sendfile - handle based copy
1919         9) Direct i/o
1920         10) "POSIX ACL" support
1921         11) Misc fcntls?
1922
1923         what about fixing 64 bit alignment
1924
1925         There are also various legacy SMB/CIFS requests used as is
1926
1927         From existing Lanman and NTLM dialects:
1928         --------------------------------------
1929         NEGOTIATE
1930         SESSION_SETUP_ANDX (BB which?)
1931         TREE_CONNECT_ANDX (BB which wct?)
1932         TREE_DISCONNECT (BB add volume timestamp on response)
1933         LOGOFF_ANDX
1934         DELETE (note delete open file behavior)
1935         DELETE_DIRECTORY
1936         READ_AND_X
1937         WRITE_AND_X
1938         LOCKING_AND_X (note posix lock semantics)
1939         RENAME (note rename across dirs and open file rename posix behaviors)
1940         NT_RENAME (for hardlinks) Is this good enough for all features?
1941         FIND_CLOSE2
1942         TRANSACTION2 (18 cases)
1943                 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
1944                 (BB verify that never need to set allocation size)
1945                 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
1946
1947         COPY (note support for copy across directories) - FUTURE, OPTIONAL
1948         setting/getting OS/2 EAs - FUTURE (BB can this handle
1949         setting Linux xattrs perfectly)         - OPTIONAL

1963                                         Actually need QUERY_FILE_UNIX_INFO since has inode num
1964                                         BB what about a) blksize/blkbits/blocks
