From ce735ff03349eeac9efe59c118d78f088a151ec4 Mon Sep 17 00:00:00 2001 From: Zhenzhong Duan <zhenzhong.duan@intel.com> Date: Thu, 15 Jun 2023 11:26:25 +0800 Subject: intel_iommu: Fix flag check in replay Replay doesn't notify registered notifiers but the one passed to it. So it's meaningless to check the registered notifier's synthetic flag. There is no issue currently as all replay use cases have MAP flag set, but let's be robust.
