From 77d6bd47cc2824af016086c2bd4650685b159e22 Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Fri, 18 Dec 2015 12:35:47 +1100 Subject: [PATCH] vfio: Add explicit alignments in vfio_iommu_spapr_tce_create The vfio_iommu_spapr_tce_create struct has 4x32bit and 2x64bit fields which should have resulted in sizeof(fio_iommu_spapr_tce_create) equal to 32 bytes. However due to the gcc's default alignment, the actual size of this struct is 40 bytes. This fills gaps with __resv1/2 fields. This should not cause any change in behavior.
