I think it would be helpful if these were either explicitly targeted for
net-next without Fixes tags (the assumed state of affairs as-is).

	Subject: [Patch x/n net-next] ...

Or targeted at net, with Fixes tags

	Subject: [Patch x/n net] ...

I guess that in theory these are fixes, as resource leaks could occur.
But perhaps that is more theory that practice. I am unsure.

I agree that would be nice, it's the usual practice for Networking
patchsets with more than one patch.

The above aside, I looked over the code changes
and I agree they are correct.
