2456 | For better POSIX semantics from Linux client, (even better |

2458 | |
2459 | 1) PosixCreateX - to set and return the mode, inode#, device info and |
2460 | perhaps add a CreateDevice - to create Pipes and other special .inodes |
2461 | Also note POSIX open flags |
2462 | 2) Close - to return the last write time to do cache across close |
2463 | more safely |
2464 | 3) FindFirst return unique inode number - what about resume key, two |
2465 | forms short (matches readdir) and full (enough info to cache inodes) |
2466 | 4) Mkdir - set mode |
2467 | |
2468 | And under consideration: |
2469 | 5) FindClose2 (return nanosecond timestamp ??) |
2470 | 6) Use nanosecond timestamps throughout all time fields if |
2471 | corresponding attribute flag is set |

2493 | TRANSACTION2 (18 cases) |
2494 | SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2 |
