[ Upstream commit 18cdd2f0998a4967b1fff4c43ed9aef049e42c39 ]

Since the writer-side lock is taken here, we do not need to open an RCU read-side critical section, instead we can use rtnl_dereference() to tell lockdep we are serialized with concurrent writes.

This is cleanup, not a bugfix. We should not have it in 5.10.

Agreed, looks like I missed this one when replying to Sasha for all the others.

Ah, I do see that I did in fact respond to this already. https://lore.kernel.org/lkml/20221010133337.4q75fsa6m2v5ttk7@skbuf/

Not sure how you put your eyes on this particular patch?
