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

+
+ 1) PosixCreateX - to set and return the mode, inode#, device info and
+ perhaps add a CreateDevice - to create Pipes and other special .inodes
+ Also note POSIX open flags
+ 2) Close - to return the last write time to do cache across close
+ more safely
+ 3) FindFirst return unique inode number - what about resume key, two
+ forms short (matches readdir) and full (enough info to cache inodes)
+ 4) Mkdir - set mode
+
+ And under consideration:
+ 5) FindClose2 (return nanosecond timestamp ??)
+ 6) Use nanosecond timestamps throughout all time fields if
+ corresponding attribute flag is set
+ 7) sendfile - handle based copy
+
+ what about fixing 64 bit alignment

+ LOGOFF_ANDX
+ DELETE (note delete open file behavior)
+ DELETE_DIRECTORY
+ READ_AND_X
+ WRITE_AND_X
+ LOCKING_AND_X (note posix lock semantics)
+ RENAME (note rename across dirs and open file rename posix behaviors)
+ NT_RENAME (for hardlinks) Is this good enough for all features?
+ FIND_CLOSE2
+ TRANSACTION2 (18 cases)
+ SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
+ (BB verify that never need to set allocation size)
+ SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
+ Unix ext?)
+
+ COPY (note support for copy across directories) - FUTURE, OPTIONAL
+ setting/getting OS/2 EAs - FUTURE (BB can this handle
+ setting Linux xattrs perfectly) - OPTIONAL
+ dnotify - FUTURE, OPTIONAL
+ quota - FUTURE, OPTIONAL
+
+ Note that various requests implemented for NT interop such as
