2494 For better POSIX semantics from Linux client, (even better
2495 than the existing CIFS Unix Extensions) we need updated PDUs for:
2497 1) PosixCreateX - to set and return the mode, inode#, device info and
2498 perhaps add a CreateDevice - to create Pipes and other special .inodes
2499 Also note POSIX open flags
2500 2) Close - to return the last write time to do cache across close
2502 3) FindFirst return unique inode number - what about resume key, two
2503 forms short (matches readdir) and full (enough info to cache inodes)
2506 And under consideration:
2507 5) FindClose2 (return nanosecond timestamp ??)
2508 6) Use nanosecond timestamps throughout all time fields if
2509 corresponding attribute flag is set
2510 7) sendfile - handle based copy
2514 what about fixing 64 bit alignment

2522 TREE_CONNECT_ANDX (BB which wct?)
2523 TREE_DISCONNECT (BB add volume timestamp on response)
2525 DELETE (note delete open file behavior)
2529 LOCKING_AND_X (note posix lock semantics)
2530 RENAME (note rename across dirs and open file rename posix behaviors)
2531 NT_RENAME (for hardlinks) Is this good enough for all features?
2533 TRANSACTION2 (18 cases)
2534 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2535 (BB verify that never need to set allocation size)
2536 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2539 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2540 setting/getting OS/2 EAs - FUTURE (BB can this handle
