I haven't seen it before, and it doesn't look like anything changed here lately. I think your test must have got unlucky to hit one of the rdma_destroy_id paths. It looks like a false positive from lockdep as these are never the same lock. Perhaps it could be fixed by lifting the mutex_unlock to before the rdma_destroy_id ? Would need some study Jason
