2337 For better POSIX semantics from Linux client, (even better

2340 1) PosixCreateX - to set and return the mode, inode#, device info and
2341 perhaps add a CreateDevice - to create Pipes and other special .inodes
2342 Also note POSIX open flags
2343 2) Close - to return the last write time to do cache across close
2344 more safely
2345 3) FindFirst return unique inode number - what about resume key, two
2346 forms short (matches readdir) and full (enough info to cache inodes)
2347 4) Mkdir - set mode
2348
2349 And under consideration:
2350 5) FindClose2 (return nanosecond timestamp ??)
2351 6) Use nanosecond timestamps throughout all time fields if
2352 corresponding attribute flag is set
2353 7) sendfile - handle based copy

2372 LOCKING_AND_X (note posix lock semantics)
2373 RENAME (note rename across dirs and open file rename posix behaviors)
2374 NT_RENAME (for hardlinks) Is this good enough for all features?
2375 FIND_CLOSE2
2376 TRANSACTION2 (18 cases)
2377 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2378 (BB verify that never need to set allocation size)
