[PATCH] mm/balloon_compaction: suppress allocation warnings

From: Nadav Amit
Date: Tue Aug 20 2019 - 12:37:35 EST


There is no reason to print warnings when balloon page allocation fails,
as they are expected and can be handled gracefully. Since VMware
balloon now uses balloon-compaction infrastructure, and suppressed these
warnings before, it is also beneficial to suppress these warnings to
keep the same behavior that the balloon had before.
