922 | This request tries to open, fsync and close the given path. This is a |
|
|
923 | composite request intended tosync directories after directory operations |
|
|
924 | (E.g. rename). This might not work on all operating systems or have any |
|
|
925 | specific effect, but usually it makes sure that directory changes get |
