This patchset incorporates support for adding and removal of memory regions to vhost-user back-end from a virtio front end and the corresponsing supporting functions. The max number of regions supported has also been increased from 8 to 128. This has been extensively tested with multiple instances of fio when running with spdk and qemu performing add/removal of memory regions to vhost testpmd.
