Thank you Andy for the review.

I understand your point about refactoring if pattern is repeated to simply things.

Also, while revisiting the changes, I noticed that unintended mistake where list_del() was replaced with list_add_tail() in couple of place during guard() conversion. I'll fix that in v4 along with suggestions and input from you and Jonathan.

I’ll send an updated version shortly.
