CVE-2023-54283

A data race was found in the BPF LRU list implementation. Concurrent access to node->ref without proper memory barriers triggers KCSAN warnings, though the race is benign as the reference value does not need to be precise.

This is a benign data race reported by KCSAN (Kernel Concurrency Sanitizer). The fix improves code correctness by using READ_ONCE/WRITE_ONCE but the original behavior was functionally acceptable for this use case.
