Since commit 33d268ed ("VMware balloon: Do not limit the amount of frees and allocations in non-sleep mode."), the allocations are not increased, and therefore balloon inflation rate limiting is in practice broken. While we can restore rate limiting, in practice we see that it can result in adverse effect, as the hypervisor throttles down the VM if it does not respond well enough, or alternatively causes it to perform very poorly as the host swaps out the VM memory. Throttling the VM down can even have a cascading effect, in which the VM reclaims memory even slower and consequentially throttled down even further. We therefore remove all the rate limiting mechanisms, including the slow allocation cycles, as they are likely to do more harm than good. Fixes: 33d268ed ("VMware balloon: Do not limit the amount of frees and allocations in non-sleep mode.")
