From 22f88475b62ac826acae2f77c3e1bd9543e87b2a Mon Sep 17 00:00:00 2001 From: "K. Y. Srinivasan" Date: Fri, 9 Jan 2015 23:54:30 -0800 Subject: [PATCH] Drivers: hv: hv_balloon: Fix a locking bug in the balloon driver We support memory hot-add in the Hyper-V balloon driver by hot adding an appropriately sized and aligned region and controlling the on-lining of pages within that region based on the pages that the host wants us to online. We do this because the granularity and alignment requirements in Linux are different from what Windows expects. The state to manage the onlining of pages needs to be correctly protected. Fix this bug. Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman --- Reading git-format-patch failed
