Details

Summary

The previous llnode field is moved inside another field node.

This node field is a struct __call_single_node in Linux. Here, we
simply add an anonymous struct with the llnode field inside. That
field's new name is llist now.

struct irq_work was changed in an incompatible way. I'm thinking of adding a
#define beside the new structure so that drivers can check it to determine
how to use it, and thus have a single code base working with multiple versions
of FreeBSD. What do you think?

Anonymous union of struct node and struct llnode?

I think something like this will work. It's not pretty but kills compilation breakage.

union {
	struct llist_node llnode;
	struct {
		struct llist_node llist;
	} node;
};

Good idea @wulf and @hselasky! I just updated the patch.
