2354 For better POSIX semantics from Linux client, (even better

2357 1) PosixCreateX - to set and return the mode, inode#, device info and
2358 perhaps add a CreateDevice - to create Pipes and other special .inodes
2359 Also note POSIX open flags
2360 2) Close - to return the last write time to do cache across close
2361 more safely
2362 3) FindFirst return unique inode number - what about resume key, two
2363 forms short (matches readdir) and full (enough info to cache inodes)
2364 4) Mkdir - set mode
2365
2366 And under consideration:
2367 5) FindClose2 (return nanosecond timestamp ??)
2368 6) Use nanosecond timestamps throughout all time fields if
2369 corresponding attribute flag is set
2370 7) sendfile - handle based copy

2389 LOCKING_AND_X (note posix lock semantics)
2390 RENAME (note rename across dirs and open file rename posix behaviors)
2391 NT_RENAME (for hardlinks) Is this good enough for all features?

2393 TRANSACTION2 (18 cases)
2394 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2395 (BB verify that never need to set allocation size)
