From 89dc52946a165b5396d4b84717d36ded8c5783c7 Mon Sep 17 00:00:00 2001 From: Ben Gardon Date: Tue, 12 Jan 2021 13:42:49 -0800 Subject: [PATCH] KVM: selftests: Avoid flooding debug log while populating memory Peter Xu pointed out that a log message printed while waiting for the memory population phase of the dirty_log_perf_test will flood the debug logs as there is no delay after printing the message. Since the message does not provide much value anyway, remove it.
