In order to avoid such races the call of fuse_uring_add_to_pq() is moved after the copy operations and just before completing the io-uring request - malicious userspace cannot find the request anymore until all prepration work in fuse-client/kernel is completed.</p> <p>This also moves fuse_uring_add_to_pq() a bit up in the code to avoid a forward declaration.
