[PATCH v4 1/2] virtio_balloon: Restore the entire balloon after the system freeze

fill_balloon() and leak_balloon() manipulate only a limited number of pages in one call. This is the reason why remove_common() calls leak_balloon() in a while cycle. remove_common() is called also when the system is being frozen. But fill_balloon() is called only once when the system is being

[PATCH v4 2/2] virtio_balloon: Use a workqueue instead of "vballoon" kthread

From: Petr Mladek This patch moves the deferred work from the "vballoon" kthread into a system freezable workqueue. We do not need to maintain and run a dedicated kthread. Also the event driven workqueues API makes the logic much easier. Especially, we do not longer need an own

[PATCH v4 0/2] virtio_balloon: Fix restore and convert to workqueue

[PATCH 4/6] Input: Remove vmmouse port reservation

This port is used by quite a few guest-to-host communication capabilities, e.g. getting configuration, logging, etc. Currently multiple kernel modules, and one or more priviledged guest user mode app, e.g. open-vm-tools, use this port without reservation. It was determined that no reservation is
