From: Vitaly Kuznetsov Date: Sun, 1 May 2016 02:21:36 +0000 (-0700) Subject: Drivers: hv: balloon: reset host_specified_ha_region X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d19a55d6ed5bf0ffe553df2d8bf91d054ddf2d76;p=openwrt%2Fstaging%2Fblogic.git Drivers: hv: balloon: reset host_specified_ha_region We set host_specified_ha_region = true on certain request but this is a global state which stays 'true' forever. We need to reset it when we receive a request where ha_region is not specified. I did not see any real issues, the bug was found by code inspection. Signed-off-by: Vitaly Kuznetsov Signed-off-by: K.
