[PATCH 0/3] rcu: Detect accidental reuse of rcu head

Posted by Peter Xu 1 month, 2 weeks ago

This is an idea suggested by Peter Maydell:

https://lore.kernel.org/all/CAFEAcA--K0=EJNNvj98i=ewGY=tN3u4S0+fNb9kJpYynzjHEhw@mail.gmail.com/

After this small series applied, we should be able to assert on misuse of
accidental (wrong) re-use on a rcu head.

Please review, thanks.
