[PATCH v3 0/5] Support add/remove memory region & get-max-slots

[Pravin M Bathija]

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). Supporting functions corresponding to
these message functions have been implemented in the interest of writing
optimized code. Older functions pasrt 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.

  vhost: add user to mailmap and define to vhost hdr
  vhost_user: header defines for add/rem mem region
  vhost_user: Function defs for add/rem mem regions
  vhost_user: support function defines for back-end
  vhost_user: Increase number of memory regions
