[PATCH 0/3] virtio: balloon: cleanups and a fix
Hello,
The main fix is to update the host with the current balloon value on
module removal after deflating the balloon. Without the fix, the host
has the wrong idea of the ballooned memory in the guest. This is
patch 2.
Patches 1 and 3 are cleanups with no effective code change.
Please apply,

[PATCH v1 0/2] virtio-balloon: tweak config_changed
...irtio-ccw doesn't work with accessing to the config registers
inside an interrupt context, this patch series avoids that issue by
moving the config register accesses to the related workqueue contexts.

[PATCH v3 0/2] virtio-balloon: some improvements
This series is split from the "Virtio-balloon: support free page
reporting" series to make some improvements.
ChangeLog:
v2->v3:
- shrink the balloon pages according to the amount requested by the
claimer, instead of using a user specified number;
v1->v2:
- register the shrinker when VIRTIO_BALLOON_F_DEFLATE_ON_OOM is
negotiated.
