From c96b8c0e39330e15ad020d332f1fbf458a3ab047 Mon Sep 17 00:00:00 2001 From: Stefano Stabellini Date: Thu, 6 Feb 2025 20:49:15 +0100 Subject: [PATCH] xen: No need to flush the mapcache for grants On IOREQ_TYPE_INVALIDATE we need to invalidate the mapcache for regular mappings. Since recently we started reusing the mapcache also to keep track of grants mappings. However, there is no need to remove grant mappings on IOREQ_TYPE_INVALIDATE requests, we shouldn't do that. So remove the function call. Fixes: 9ecdd4bf08 (xen: mapcache: Add support for grant mappings) Cc: qemu-stable@nongnu.org Reported-by: Olaf Hering Reviewed-by: Edgar E.
