2474 For better POSIX semantics from Linux client, (even better
2475 than the existing CIFS Unix Extensions) we need updated PDUs for:
2477 1) PosixCreateX - to set and return the mode, inode#, device info and
2478 perhaps add a CreateDevice - to create Pipes and other special .inodes
2479 Also note POSIX open flags
2480 2) Close - to return the last write time to do cache across close
2482 3) FindFirst return unique inode number - what about resume key, two
2483 forms short (matches readdir) and full (enough info to cache inodes)
2486 And under consideration:
2487 5) FindClose2 (return nanosecond timestamp ??)
2488 6) Use nanosecond timestamps throughout all time fields if
2489 corresponding attribute flag is set
2490 7) sendfile - handle based copy
2494 what about fixing 64 bit alignment

2502 TREE_CONNECT_ANDX (BB which wct?)
2503 TREE_DISCONNECT (BB add volume timestamp on response)
2505 DELETE (note delete open file behavior)
2509 LOCKING_AND_X (note posix lock semantics)
2510 RENAME (note rename across dirs and open file rename posix behaviors)
2511 NT_RENAME (for hardlinks) Is this good enough for all features?
2513 TRANSACTION2 (18 cases)
2514 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2515 (BB verify that never need to set allocation size)
2516 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2519 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2520 setting/getting OS/2 EAs - FUTURE (BB can this handle
2521 setting Linux xattrs perfectly) - OPTIONAL
2522 dnotify - FUTURE, OPTIONAL
2523 quota - FUTURE, OPTIONAL
