2461 For better POSIX semantics from Linux client, (even better
2462 than the existing CIFS Unix Extensions) we need updated PDUs for:
2464 1) PosixCreateX - to set and return the mode, inode#, device info and
2465 perhaps add a CreateDevice - to create Pipes and other special .inodes
2466 Also note POSIX open flags
2467 2) Close - to return the last write time to do cache across close
2469 3) FindFirst return unique inode number - what about resume key, two
2470 forms short (matches readdir) and full (enough info to cache inodes)
2473 And under consideration:
2474 5) FindClose2 (return nanosecond timestamp ??)
2475 6) Use nanosecond timestamps throughout all time fields if
2476 corresponding attribute flag is set
2477 7) sendfile - handle based copy
2479 what about fixing 64 bit alignment

2487 TREE_CONNECT_ANDX (BB which wct?)
2488 TREE_DISCONNECT (BB add volume timestamp on response)
2490 DELETE (note delete open file behavior)
2494 LOCKING_AND_X (note posix lock semantics)
2495 RENAME (note rename across dirs and open file rename posix behaviors)
2496 NT_RENAME (for hardlinks) Is this good enough for all features?
2498 TRANSACTION2 (18 cases)
2499 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2500 (BB verify that never need to set allocation size)
2501 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
