On the Hyper-V platform, the host has a policy engine to balance > the available physical memory amongst all competing virtual machines > hosted on a given node. This policy engine is driven by a number of metrics > including the memory commitment reported by the guests. The balloon driver > for Linux on Hyper-V will use this function to retrieve guest memory commitment. > This function is also used in Xen self ballooning code. > > Signed-off-by: K. Y. Srinivasan <kys@xxxxxxxxxxxxx> The patch to the Xen selfballoon driver is unnecessary, but is one step in the direction of module support for this driver so I am fine whether the patch is included here or not.
