2377 | For better POSIX semantics from Linux client, (even better |

50c2f753 | 2379 | |
1da177e4 LT |
2380 | 1) PosixCreateX - to set and return the mode, inode#, device info and |
2381 | perhaps add a CreateDevice - to create Pipes and other special .inodes | |
2382 | Also note POSIX open flags | |
50c2f753 | 2383 | 2) Close - to return the last write time to do cache across close |
87f440e7 | 2384 | more safely |
50c2f753 | 2385 | 3) FindFirst return unique inode number - what about resume key, two |
1982c344 SF |
2386 | forms short (matches readdir) and full (enough info to cache inodes) |
2387 | 4) Mkdir - set mode | |
50c2f753 SF |
2388 | |
2389 | And under consideration: | |
1982c344 | 2390 | 5) FindClose2 (return nanosecond timestamp ??) |
50c2f753 | 2391 | 6) Use nanosecond timestamps throughout all time fields if |
1da177e4 | 2392 | corresponding attribute flag is set |
1982c344 SF |
2393 | 7) sendfile - handle based copy |
2394 | 8) Direct i/o | |
2395 | 9) Misc fcntls? | |
50c2f753 | 2396 | |
1da177e4 | 2397 | what about fixing 64 bit alignment |
