io_fsync() calls the syscall io_submit(). when doing IO_CMD_FSYNC and IO_CMD_FDSYNC, Linux kernel will involve the filesystem's aio_fsync and aio_fdsync operations, and if the filesystem doesn't implement these two operations, it will return -EINVAL, this is the error you meet here. In fact, the syscall io_submit() in kernel is asynchronous, and the performance is better than adding a outstanding asynchronous aio_* operations. In general, this CMD is not implemented in Linux kernel.
