2276 For better POSIX semantics from Linux client, (even better

2278
2279 1) PosixCreateX - to set and return the mode, inode#, device info and
2280 perhaps add a CreateDevice - to create Pipes and other special .inodes
2281 Also note POSIX open flags
2282 2) Close - to return the last write time to do cache across close
2283 more safely
2284 3) FindFirst return unique inode number - what about resume key, two
2285 forms short (matches readdir) and full (enough info to cache inodes)
2286 4) Mkdir - set mode
2287
2288 And under consideration:
2289 5) FindClose2 (return nanosecond timestamp ??)
2290 6) Use nanosecond timestamps throughout all time fields if
2291 corresponding attribute flag is set
2292 7) sendfile - handle based copy
2293 8) Direct i/o
2294 9) Misc fcntls?

2304 TREE_CONNECT_ANDX (BB which wct?)

2306 LOGOFF_ANDX
2307 DELETE (note delete open file behavior)
2308 DELETE_DIRECTORY
2309 READ_AND_X
2310 WRITE_AND_X
2311 LOCKING_AND_X (note posix lock semantics)
2312 RENAME (note rename across dirs and open file rename posix behaviors)
2313 NT_RENAME (for hardlinks) Is this good enough for all features?
2314 FIND_CLOSE2
2315 TRANSACTION2 (18 cases)
2316 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2317 (BB verify that never need to set allocation size)
2318 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2319 Unix ext?)
2320
2321 COPY (note support for copy across directories) - FUTURE, OPTIONAL

2323 setting Linux xattrs perfectly) - OPTIONAL
2324 dnotify - FUTURE, OPTIONAL
