Support fine-grained file sync #1897

Open dean-deng opened 4 years ago

Currently, there is no distinction between data sync and full file sync (for example, Fdatasync simply calls Fsync). While correct, this unnecessarily flushes metadata.

We also do not support partial file sync (e.g. sync_file_range does a full file sync).
