Subject: [PATCH v2 0/3] rcu: Detect accidental reuse of rcu head
Date: Tue, 14 Oct 2025 15:19:41 -0400 [thread overview]
Message-ID: <20251014191944.2225735-1-peterx@redhat.com> (raw)
v2:
- Change patch 2 subject and wording to avoid mentioning "double free" [PeterM]
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.
