[PATCH 5.4 013/151] hv_balloon: disable warning when floor reached
From: Greg Kroah-Hartman
Date: Tue Nov 17 2020 - 08:24:21 EST
From: Olaf Hering <olaf@xxxxxxxxx>
[ Upstream commit 2c3bd2a5c86fe744e8377733c5e511a5ca1e14f5 ]
It is not an error if the host requests to balloon down, but the VM
refuses to do so. Without this change a warning is logged in dmesg
every five minutes.
Fixes: b3bb97b8a49f3 ("Drivers: hv: balloon: Add logging for dynamic memory operations")
