Hi there, We are currently working on integrating io_uring into netty and found some “suprising” behaviour which seems like a bug to me. When a socket is marked as non blocking (accepted with O_NONBLOCK flag set) and there is no data to be read IORING_OP_READ should complete directly with EAGAIN or EWOULDBLOCK. This is not the case and it basically blocks forever until there is some data to read. Is this expected ? This seems to be somehow related to a bug that was fixed for IO_URING_ACCEPT with non blocking sockets: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.8&id=e697deed834de15d2322d0619d51893022c90ea2 Thanks Norman
