To avoid future mistakes, can you write down how "transform plain 
structs before pointers to structs" looks like? Is it a particular order 
of Coccinelle rules? Which part of the interdiff between the previous 
round and this round makes the difference?

On a tangent, I wondered recently, why we need oidcpy() and oidclr(). 
After all, in place of, e.g.,

	oidcpy(&pair->two->oid, &p->oid);
	oidclr(&one->oid);

we can write

	pair->two->oid = p->oid;
	one->oid = null_oid;

Is there a particular reason *not* to make this transition? I find the 
latter less cluttered with equal clarity.
