We're constantly developing and improving KVM, implementing new awesome
features or simply fixing bugs in the existing code.
But do people actually use that new code? Are we maybe writing it all in
vain? Wouldn't it be nice to have some feeling for the number of users
actually using our code?
This patch enables us to stress test our automated test suite and at
the same time figure out if we actually have users. When using a new
kernel with this patch applied, the user will automatically send feedback,
telling us that there are people out there, trying recent versions!
