From f6686036947316fd5b4c08c515735dbccf6d2dbc Mon Sep 17 00:00:00 2001 From: Sebastien Boeuf Date: Fri, 20 Dec 2019 14:06:09 +0100 Subject: [PATCH] ci: Fix flaky test_memory_mergeable_on test Because we don't always reach the expected footprint improvements with KSM, let's review the numbers. By reducing the expectations and increasing the amount of pages to scan, this should stabilize the CI.
