2385 Also note POSIX open flags
2386 2) Close - to return the last write time to do cache across close
2387 more safely
2388 3) FindFirst return unique inode number - what about resume key, two
2389 forms short (matches readdir) and full (enough info to cache inodes)
2390 4) Mkdir - set mode
2391
2392 And under consideration:
2393 5) FindClose2 (return nanosecond timestamp ??)
2394 6) Use nanosecond timestamps throughout all time fields if
2395 corresponding attribute flag is set

2416 RENAME (note rename across dirs and open file rename posix behaviors)
2417 NT_RENAME (for hardlinks) Is this good enough for all features?

2419 TRANSACTION2 (18 cases)
2420 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2421 (BB verify that never need to set allocation size)
