Hi all, On RHEL7.5, running generic/465 with xfs should fail because the fix patch[1] is not merged. But on my environment[3], since the patch set[2] designed to fix generic/450 is ported into RHEL7.5, generic/465 turns into pass on my environment. I discover that various combinations of cpu and memory can lead to different results of generic/465. On environment[4], generic/465 fails. On environment[5], generic/465 passes. On other environment[6], generic/465 always fails.

The issue was reported by Yang Xu (xuyang.jy@xxxxxxxxxxxxxx) Thanks, Xiao Yang
