| 1) PosixCreateX - to set and return the mode, inode#, device info and |
| perhaps add a CreateDevice - to create Pipes and other special .inodes |
| Also note POSIX open flags |
| 2) Close - to return the last write time to do cache across close |
| more safely |
| 3) FindFirst return unique inode number - what about resume key, two |
| forms short (matches readdir) and full (enough info to cache inodes) |
| 4) Mkdir - set mode |
| |
| And under consideration: |
| 5) FindClose2 (return nanosecond timestamp ??) |
| 6) Use nanosecond timestamps throughout all time fields if |
| corresponding attribute flag is set |
| 7) sendfile - handle based copy |
| |
| what about fixing 64 bit alignment |

| LOGOFF_ANDX |
| DELETE (note delete open file behavior) |
| DELETE_DIRECTORY |
| READ_AND_X |
| WRITE_AND_X |
| LOCKING_AND_X (note posix lock semantics) |
| RENAME (note rename across dirs and open file rename posix behaviors) |
| NT_RENAME (for hardlinks) Is this good enough for all features? |
| FIND_CLOSE2 |
| TRANSACTION2 (18 cases) |
| SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2 |
| (BB verify that never need to set allocation size) |
| SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via |
| Unix ext?) |
| |
| COPY (note support for copy across directories) - FUTURE, OPTIONAL |
| setting/getting OS/2 EAs - FUTURE (BB can this handle |
| setting Linux xattrs perfectly) - OPTIONAL |
| dnotify - FUTURE, OPTIONAL |
| quota - FUTURE, OPTIONAL |

| Note that various requests implemented for NT interop such as |
