Amit Shah (3):
balloon: Make functions return 0 on OK, -1 on error.
balloon: report error if ballooning operation fails
virtio-balloon: report error if balloon driver in guest not availabl
Current semantics of 1 on OK and 0 on error are slightly weird.
qemu_balloon() and qemu_balloon_stats() do this. Other functions in the
file use the standard 0 and -1 return values. This commit makes the
file consistent in returning such values.

was still
updated, resulting in the ballooning value being applied to the guest
after the guest loads the balloon module. This may not be the desirable
thing to do at this later stage.

Ballooning operations can fail (e.g. driver in guest not available).
Let the user know of such an error condition instead of silently
ignoring errors.

after a migration, we don't ever think of looking at messages on the

There's one report of migration breaking due to missing MSR_TSC_AUX
save/restore. Fix this by adding a new subsection that saves the state
of this MSR.

Hello all,
For the 2.4 release, we tried a little experiment.
I asked maintainers who had pull reqs merged in the 2.4 release to
give me a few talking points for their subsystem via email. Since the
