Drivers: hv: balloon: Make adjustments to the pressure report
The host expects that the pressure report includes the pressure due to the pages that have been ballooned. Make necessary adjustments to reflect that. Also, include the free memory information in the pressure report. Signed-off-by: K. Y. Srinivasan <kys@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
