2323 For better POSIX semantics from Linux client, (even better

2325
2326 1) PosixCreateX - to set and return the mode, inode#, device info and
2327 perhaps add a CreateDevice - to create Pipes and other special .inodes
2328 Also note POSIX open flags
2329 2) Close - to return the last write time to do cache across close
2330 more safely
2331 3) FindFirst return unique inode number - what about resume key, two
2332 forms short (matches readdir) and full (enough info to cache inodes)
2333 4) Mkdir - set mode
2334
2335 And under consideration:
2336 5) FindClose2 (return nanosecond timestamp ??)
2337 6) Use nanosecond timestamps throughout all time fields if
2338 corresponding attribute flag is set
2339 7) sendfile - handle based copy
2340 8) Direct i/o
2341 9) Misc fcntls?

2357 WRITE_AND_X
2358 LOCKING_AND_X (note posix lock semantics)
2359 RENAME (note rename across dirs and open file rename posix behaviors)
2360 NT_RENAME (for hardlinks) Is this good enough for all features?
2361 FIND_CLOSE2
2362 TRANSACTION2 (18 cases)
2363 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2364 (BB verify that never need to set allocation size)
2365 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
