It would be good to get comments.. PostgreSQL is a potential user of async fdatasync, fsync, sync_file_range and potentially readahead, write, read. First tests with Dave's async fsync/fsync_range are positive, so are the results with a self-hacked async sync_file_range (although I'm kinda thinking that it shouldn't really require to be used asynchronously). I rather doubt openat, unlink et al are going to be interesting for *us*, the requires structural changes would be too bit. But obviously that doesn't mean anything for others. Andres
