+ Also note POSIX open flags
+ 2) Close - to return the last write time to do cache across close more safely
+ 3) PosixQFSInfo - to return statfs info
+ 4) FindFirst return unique inode number - what about resume key, two forms short (matches readdir) and full (enough info to cache inodes)
+ 5) Mkdir - set mode
+
+ And under consideration:
+ 6) FindClose2 (return nanosecond timestamp ??)
+ 7) Use nanosecond timestamps throughout all time fields if
+ corresponding attribute flag is set
+ 8) sendfile - handle based copy
+ 9) Direct i/o
+ 10) "POSIX ACL" support
+ 11) Misc fcntls?

+ 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
