描述

It would be really nice if Mutex had deadlock detection (including via a feature flag). Especially in an async context where it's hard to peer into the state of tasks, these can be exceptionally hard to debug.

parking_lot does this for its synchronous locks, though it requires you to trigger detection manually on another thread.

研究方向
Investigate parking lot's deadlock detection implementation (https://amanieu.github.io/parking lot/parking lot/deadlock/index.html) and adapt it to the async context of futures::lock::Mutex. Consider using a feature flag to enable detection. Review existing discussions in issue #2133 and any related PRs. The goal is to provide a mechanism to detect and report deadlocks, aiding debugging in async environments.
