From 02fa5d7b17a761f53ef1eedfc254e1f33bd226b0 Mon Sep 17 00:00:00 2001 From: Nadav Amit Date: Tue, 20 Aug 2019 02:16:46 -0700 Subject: [PATCH] mm/balloon_compaction: suppress allocation warnings 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.
