io_uring does provide the primitives needed; there's IORING_OP_FSYNC (with IORING_FSYNC_DATASYNC to weaken from fsync to fdatasync) and IORING_OP_SYNC_FILE_RANGE for flushing caches asynchronously, and the IOSQE_IO_DRAIN and IOSQE_IO_LINK flags to order io_uring operations with respect to each other so that you can issue the fsync after all the related writes have been done.
