From 82386d4a0f19ff1e6a04e29f104da1d12269539e Mon Sep 17 00:00:00 2001 From: Klaus Jensen Date: Wed, 29 Jul 2020 21:55:37 +0200 Subject: hw/block/nvme: remove explicit qsg/iov parameters Since nvme_map_prp always operate on the request-scoped qsg/iovs, just pass a single pointer to the NvmeRequest instead of two for each of the qsg and iov.
