Hi,

v5 is basically the same as v4, only that I’ve dropped the patch
deprecating F_STATUS (which doesn’t affect the rest of the series), that
I’ve amended the documentation in patch 1 as suggested by Stefan and
with help from Michael, and that I’ve rebased everything on top of the
F_SHARED_OBJECT changes that have been merged upstream.


git-backport-diff against v4:

Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively

001/7:[0029] [FC] 'vhost-user.rst: Improve [GS]ET_VRING_BASE doc'
002/7:[----] [--] 'vhost-user.rst: Clarify enabling/disabling vrings'
003/7:[----] [--] 'vhost-user.rst: Introduce suspended state'
004/7:[0006] [FC] 'vhost-user.rst: Migrating back-end-internal state'
005/7:[0007] [FC] 'vhost-user: Interface for migration state transfer'
006/7:[----] [--] 'vhost: Add high-level state save/load functions'
007/7:[----] [--] 'vhost-user-fs: Implement internal migration'


Changes patch by patch:
- Patch 1: Amended documentation
- Patches 4 and 5: Bumped feature bit and command values as necessary so
  as not to conflict with F_SHARED_OBJECT

Ping – both of the dependencies are merged.
