2272 For better POSIX semantics from Linux client, (even better

2274
2275 1) PosixCreateX - to set and return the mode, inode#, device info and
2276 perhaps add a CreateDevice - to create Pipes and other special .inodes
2277 Also note POSIX open flags
2278 2) Close - to return the last write time to do cache across close
2279 more safely
2280 3) FindFirst return unique inode number - what about resume key, two
2281 forms short (matches readdir) and full (enough info to cache inodes)
2282 4) Mkdir - set mode
2283
2284 And under consideration:
2285 5) FindClose2 (return nanosecond timestamp ??)
2286 6) Use nanosecond timestamps throughout all time fields if
2287 corresponding attribute flag is set
2288 7) sendfile - handle based copy

2297 SESSION_SETUP_ANDX (BB which?)
2298 TREE_CONNECT_ANDX (BB which wct?)
2299 TREE_DISCONNECT (BB add volume timestamp on response)
2300 LOGOFF_ANDX
2301 DELETE (note delete open file behavior)
2302 DELETE_DIRECTORY
2303 READ_AND_X
2304 WRITE_AND_X
2305 LOCKING_AND_X (note posix lock semantics)
2306 RENAME (note rename across dirs and open file rename posix behaviors)
2307 NT_RENAME (for hardlinks) Is this good enough for all features?
2308 FIND_CLOSE2
2309 TRANSACTION2 (18 cases)
2310 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2311 (BB verify that never need to set allocation size)
2312 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2313 Unix ext?)
2314
2315 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2316 setting/getting OS/2 EAs - FUTURE (BB can this handle
2317 setting Linux xattrs perfectly) - OPTIONAL
2318 dnotify - FUTURE, OPTIONAL
2319 quota - FUTURE, OPTIONAL
