file_operations->uring_cmd is a file private handler. This is somewhat similar to ioctl but hopefully a lot more sane and useful as it can be used to enable many io_uring capabilities for the underlying operation. IORING_OP_URING_CMD is a file private kind of request. io_uring doesn't know what is in this command type, it's for the provider of ->uring_cmd() to deal with.
