From 94aedac49d92b22995d7b9092c6551b8b9924320 Mon Sep 17 00:00:00 2001 From: Dafna Hirschfeld Date: Thu, 4 Nov 2021 09:16:20 +0200 Subject: [PATCH] iommu: Log iova range in map/unmap trace events In case of an iommu page fault, the faulting iova is logged in trace_io_page_fault. It is therefore convenient to log the iova range in mapping/unmapping trace events so that it is easier to see if the faulting iova was recently in any of those ranges.
