2271 For better POSIX semantics from Linux client, (even better

2273
2274 1) PosixCreateX - to set and return the mode, inode#, device info and
2275 perhaps add a CreateDevice - to create Pipes and other special .inodes
2276 Also note POSIX open flags
2277 2) Close - to return the last write time to do cache across close
2278 more safely
2279 3) FindFirst return unique inode number - what about resume key, two
2280 forms short (matches readdir) and full (enough info to cache inodes)
2281 4) Mkdir - set mode
2282
2283 And under consideration:
2284 5) FindClose2 (return nanosecond timestamp ??)
2285 6) Use nanosecond timestamps throughout all time fields if
2286 corresponding attribute flag is set
2287 7) sendfile - handle based copy
2288 8) Direct i/o
2289 9) Misc fcntls?

2291 what about fixing 64 bit alignment

2299 TREE_CONNECT_ANDX (BB which wct?)

2301 LOGOFF_ANDX
2302 DELETE (note delete open file behavior)
2303 DELETE_DIRECTORY
2304 READ_AND_X
2305 WRITE_AND_X
2306 LOCKING_AND_X (note posix lock semantics)
2307 RENAME (note rename across dirs and open file rename posix behaviors)
2308 NT_RENAME (for hardlinks) Is this good enough for all features?
2309 FIND_CLOSE2
2310 TRANSACTION2 (18 cases)
2311 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2312 (BB verify that never need to set allocation size)
2313 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2314 Unix ext?)
2315
2316 COPY (note support for copy across directories) - FUTURE, OPTIONAL

2318 setting Linux xattrs perfectly) - OPTIONAL
2319 dnotify - FUTURE, OPTIONAL
