2380         For better POSIX semantics from Linux client, (even better

2382
2383         1) PosixCreateX - to set and return the mode, inode#, device info and
2384         perhaps add a CreateDevice - to create Pipes and other special .inodes
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
2396         7) sendfile - handle based copy
2397         8) Direct i/o
2398         9) Misc fcntls?
