[Qemu-devel] [RFC PATCH 4/8] memory: rename *_notify_iommu*


From: Peter Xu
Subject: [Qemu-devel] [RFC PATCH 4/8] memory: rename *_notify_iommu*
Date: Thu, 27 Apr 2017 17:34:16 +0800

Actually it's notifying IOTLB updates (map, or unmap). Let's be explicit
on the wording - replacing it with *_notify_iotlb*.
