From: Yi Liu <yi.l.liu@xxxxxxxxx>
[ Upstream commit 84798f2849942bb5e8817417adfdfa6241df2835 ]
struct iommu_ioas_copy, struct iommu_option and struct iommu_vfio_ioas are
missed in ucmd_buffer. Although they are smaller than the size of
ucmd_buffer, it is safer to list them in ucmd_buffer explicitly.
Fixes: aad37e71d5c4 ("iommufd: IOCTLs for the io_pagetable")
Fixes: d624d6652a65 ("iommufd: vfio container FD ioctl compatibility")
