2533         For better POSIX semantics from Linux client, (even better
2534         than the existing CIFS Unix Extensions) we need updated PDUs for:
2535
2536         1) PosixCreateX - to set and return the mode, inode#, device info and
2537         perhaps add a CreateDevice - to create Pipes and other special .inodes
2538         Also note POSIX open flags
2539         2) Close - to return the last write time to do cache across close
2540                 more safely
2541         3) FindFirst return unique inode number - what about resume key, two
2542         forms short (matches readdir) and full (enough info to cache inodes)
2543         4) Mkdir - set mode
2544
2545         And under consideration:
2546         5) FindClose2 (return nanosecond timestamp ??)
2547         6) Use nanosecond timestamps throughout all time fields if
2548            corresponding attribute flag is set
2549         7) sendfile - handle based copy
2550
2551         what about fixing 64 bit alignment

2553         There are also various legacy SMB/CIFS requests used as is

2560         TREE_DISCONNECT (BB add volume timestamp on response)

2567         RENAME (note rename across dirs and open file rename posix behaviors)
