[PATCH v4 0/8] Draft, incomplete series introducing state migration

[Stefano Brivio <sbrivio@redhat.com>]

I applied what I could, and squashed a number patches, including
those from "[PATCH 0/6] More migration improvements".

I didn't test the full flow here.

David Gibson (2):
  migrate: Make more handling common rather than vhost-user specific
  migrate: Don't handle the migration channel through epoll

Stefano Brivio (6):
  flow_table: Use size in extern declaration for flowtab, export hash
    table
  Introduce facilities for guest migration on top of vhost-user
    infrastructure
  Add interfaces and configuration bits for passt-repair
  flow, tcp: Basic pre-migration source handler to dump sequence numbers
  vhost_user: Make source quit after reporting migration state
  Implement target side of migration
