Thanks, I will add both changes to v5.

One question before I send it: is there a reason to prefer bool here?
All the callers only test the result for failure, so bool works for
them, but coding-style.rst (section 16) says that a function whose name
is an action should return an error-code integer. I can keep the int
return, as it is in net-next now, or go with bool as in your diff,
whichever you prefer.
