When RDMA device registration fails, the registration\nworker's err_dealloc_ctx path calls c4iw_dealloc() directly, bypassing\nc4iw_remove(), so the debugfs dentries leak and outlive the freed\nc4iw_dev.\n\nMove debugfs_remove_recursive() into c4iw_dealloc() so every path that\nfrees ctx->dev also removes its debugfs tree.","state":0,"publishedAt":"2026-09-17T16:07:30.778+00:00","modifiedAt":"2026-10-19T08:59:55.119+00:00","affected":[{"ecosystem":"Vendor
