happen if the write happens from a C program that does write(fd,

simply copying the bytes (we've already checked that size is <
IFNAMSIZ) and unconditionally zero-terminate it; of course, we also
still have to strip a trailing newline.

   allocations, so that dma-handles could be allocated in an exclusion

   tries to allocate the default domain for an iommu group and the
