Hi all

We are now four months into 4.6 development window. This is an email to keep
track of all the patch series I gathered. It is by no means complete and / or
acurate. Feel free to reply this email with new projects or correct my

= Timeline =

We are planning on a 9-month release cycle, but we could also release a bit
earlier if everything goes well (no blocker, no critical bug).

* Development start: 6 Jan 2015
<=== We are here ===>
* Feature Freeze: 10 Jul 2015
* RCs: TBD
* Release Date: 9 Oct 2015 (could release earlier)

The RCs and release will of course depend on stability and bugs, and
will therefore be fairly unpredictable.

Bug-fixes, if Acked-by by maintainer, can go anytime before the First
RC. Later on we will need to figure out the risk of regression/reward
to eliminate the possiblity of a bug introducing another bug.

= Prognosis =

The states are: none -> fair -> ok -> good -> done

none - nothing yet
fair - still working on it, patches are prototypes or RFC
ok   - patches posted, acting on review
good - some last minute pieces
done - all done, might have bugs

== Xen toolstack ==

*  Split libxc into multiple libraries (none)
   -  Ian Campbell

*  Remus using migration-v2 (good)
    RFC posted - depends on v6 of 'New Migration'
   -  Yang Hongyang


*  Migration v2 (libxl) (none)
   -  Andrew Cooper


*  COarse-grain LOck-stepping Virtual Machines in Xen (fair)
    RFC v5 posted
   -  Wen Congyang
   -  Gui Jianfeng
   -  Yang Hongyang
   -  Dong, Eddie

This should be ok:
[PATCH v6 COLO 00/15] COarse-grain LOck-stepping Virtual Machines for Non-stop Service

*  tmem migrationv2 patches. (none)
   -  Bob Liu & Andrew Cooper & David Vrabel

*  snapshot API extension (checkpointing disk) (fair)
   -  Chunyan Liu
