This patchset incorporates support for adding and removal of memory regions, getting max memory slots and other changes to vhost-user messages. These messages are sent from vhost-user front-end (qemu or libblkio) to a vhost-user back-end (dpdk, spdk). Support functions for these message functions have been implemented in the interest of writing optimized code. Older functions, part of vhost-user back-end have also been optimized using these newly defined support functions. This implementation has been extensively tested by doing Read/Write I/O from multiple instances of fio + libblkio (front-end) talking to spdk/dpdk (back-end) based drives. Also tested with qemu front-end talking to dpdk + testpmd (back-end) performing add/removal of memory regions. The last patch also includes increasing the number of memory regions from 8 to 128. This has been also extensively tested using the above test approaches.
