At least it is correct and changes automagically if x changes the type
which
struct bar *x;
x = kmalloc(sizeof(struct foo), GFP_KERNEL);
doesn't do and the compiler doesn't complain.
And the typeof() version could be written that way today but I can't
remember seeing it (in the kernel and elsewhere).
