From 769335ecb1e8fd9c4317bdff7cfd0f84af7ab2f9 Mon Sep 17 00:00:00 2001 From: Stefano Garzarella Date: Tue, 19 May 2020 15:49:42 +0200 Subject: io_uring: use io_uring_cq_ready() to check for ready cqes In qemu_luring_poll_cb() we are not using the cqe peeked from the CQ ring. We are using io_uring_peek_cqe() only to see if there are cqes ready, so we can replace it with io_uring_cq_ready().
