2494         For better POSIX semantics from Linux client, (even better
2495         than the existing CIFS Unix Extensions) we need updated PDUs for:
2496
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
2501                 more safely
2502         3) FindFirst return unique inode number - what about resume key, two
2503         forms short (matches readdir) and full (enough info to cache inodes)
2504         4) Mkdir - set mode
2505
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
2511         8) Direct i/o
2512         9) Misc fcntls?
2513
2514         what about fixing 64 bit alignment

2522         TREE_CONNECT_ANDX (BB which wct?)
2523         TREE_DISCONNECT (BB add volume timestamp on response)

2530         RENAME (note rename across dirs and open file rename posix behaviors)
2531         NT_RENAME (for hardlinks) Is this good enough for all features?
