[Qemu-devel] [PATCH 00/11] Misc migration cleanups

[Juan Quintela]

Hi

This are a bit of everything:
- Remove unneeded argumets for migration_channel_incomming
- Lots of changes to make migration.h local to only migration
  * Move self_annonce_delay() to misc.h
    I know this conflicts for announce changes from Vlad, but
    I want to remove migration.h from being exported.
  * split registrantion functions to register.h
  * Almost everything uses vmsd's for registration
  * Move constants to the places that use it
    And they are not used outside of migration/*
  * create global_state.c, as they don't belong anywhere else

ToSend:
  * RAMState is a dynamic variable on my tree
  * save_{setup,cleanup} and load_{setup,cleanup}
    Yes Kevin, that is for block layer
  * move all ram.c to use load_setup/cleanup

ToDo easy: (probably post 2.10)
  * split qapi functions from migration.c
    They don't belong there, and it would be clearer about what is configuratio 
and what is code
  * block.c and page_cache.c still use DPRINTF, they should move to use tracing
    this is easy, volunteers, please.
  * Now that it is clear what functions are exported and which not, writting 
documentation could
    be a good idea for them.

ToDo, difficult:
  * rdma.c -> this needs some love, it uses a completely different set of hooks 
that everything
    else, should have to integrate somehow everything together.
  * abstract compression, xbzrle, postcopy and rdma into something that
    is easier to understand.

Please, review.

Thanks, Juan.
