+Subject: [PATCH] linux-headers: update against 5.10 and manual clear vfio
+ dirty log series
+
+The new capability VFIO_DIRTY_LOG_MANUAL_CLEAR and the new ioctl
+VFIO_IOMMU_DIRTY_PAGES_FLAG_GET_BITMAP_NOCLEAR and
+VFIO_IOMMU_DIRTY_PAGES_FLAG_CLEAR_BITMAP have been introduced in
+the kernel, update the header to add them.

++ * supports clearing a bitmap of the smallest supported pgsize only and can be

++ * user must provide a memory area for the bitmap memory and specify its size
++ * in bitmap.size. One bit is used to represent one page consecutively starting

++ * A bit set in the bitmap indicates that the page at that offset from iova is
