charset="utf-8" From: Markus Armbruster qemu_rdma_exchange_get_response() compares int parameter @expecting with uint32_t head->type. Actual arguments are non-negative enumeration constants, RDMAControlHeader uint32_t member type, or qemu_rdma_exchange_recv() int parameter expecting. Actual arguments for the latter are non-negative enumeration constants. Change both parameters to uint32_t. In qio_channel_rdma_readv(), loop control variable @i is ssize_t, and counts from 0 up to @niov, which is size_t. Change @i to size_t. While there, make qio_channel_rdma_readv() and qio_channel_rdma_writev() more consistent: change the former's @done to ssize_t, and delete the latter's useless initialization of @len.
