I already placed my review by, but this is more of a matter of taste.

I don't think this should be a #define, but instead a static inline.
The assembly will end up as the same, but the compiler warnings will be
more helpful if it is a static inline, as we don't want
"plist_add_tail()" being shown in warnings when the developer never
typed in "_tail()".

Thus it should be:

static inline void
plist_add(struct plist_node *node, struct plist_head *head)
{
	plist_add_tail(node, head);
}

You can keep my Reviewed-by, but please make this update.
