1905 For better POSIX semantics from Linux client, (even better

1907
1908 1) PosixCreateX - to set and return the mode, inode#, device info and
1909 perhaps add a CreateDevice - to create Pipes and other special .inodes
1910 Also note POSIX open flags
1911 2) Close - to return the last write time to do cache across close more safely
1912 3) PosixQFSInfo - to return statfs info
1913 4) FindFirst return unique inode number - what about resume key, two forms short (matches readdir) and full (enough info to cache inodes)
1914 5) Mkdir - set mode
1915
1916 And under consideration:
1917 6) FindClose2 (return nanosecond timestamp ??)
1918 7) Use nanosecond timestamps throughout all time fields if
1919 corresponding attribute flag is set
1920 8) sendfile - handle based copy
1921 9) Direct i/o
1922 10) "POSIX ACL" support
1923 11) Misc fcntls?
1924
1925 what about fixing 64 bit alignment

1933 TREE_CONNECT_ANDX (BB which wct?)

1935 LOGOFF_ANDX
1936 DELETE (note delete open file behavior)
1937 DELETE_DIRECTORY
1938 READ_AND_X
1939 WRITE_AND_X
1940 LOCKING_AND_X (note posix lock semantics)
1941 RENAME (note rename across dirs and open file rename posix behaviors)
1942 NT_RENAME (for hardlinks) Is this good enough for all features?
1943 FIND_CLOSE2
1944 TRANSACTION2 (18 cases)
1945 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
1946 (BB verify that never need to set allocation size)
1947 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
1948
1949 COPY (note support for copy across directories) - FUTURE, OPTIONAL

1951 setting Linux xattrs perfectly) - OPTIONAL
1952 dnotify - FUTURE, OPTIONAL
