Y. Srinivasan" <kys@xxxxxxxxxxxxx> Date: Sun, 14 Jul 2013 22:38:12 -0700 Subject: Drivers: hv: balloon: Do not post pressure status if interrupted From: "K. Y. Srinivasan" <kys@xxxxxxxxxxxxx> commit c5e2254f8d63a6654149aa32ac5f2b7dd66a976d upstream. When we are posting pressure status, we may get interrupted and handle the un-balloon operation. In this case just don't post the status as we know the pressure status is stale. Signed-off-by: K. Y.
