From f73ca66f0d7f4371d172d6f5b1f9a00e367ba921 Mon Sep 17 00:00:00 2001 From: Mitchell Levy Date: Fri, 7 Mar 2025 15:27:01 -0800 Subject: rust: lockdep: Use Pin for all LockClassKey usages Reintroduce dynamically-allocated LockClassKeys such that they are automatically (de)registered. Require that all usages of LockClassKeys ensure that they are Pin'd. Currently, only `'static` LockClassKeys are supported, so Pin is redundant. However, it is intended that dynamically-allocated LockClassKeys will eventually be supported, so using Pin from the outset will make that change simpler.
