Hi all, After merging the bpf-next tree, today's linux-next build (htmldocs) produced this warning: Documentation/bpf/graph_ds_impl.rst:62: ERROR: Error in "code-block" directive: maximum 1 argument(s) allowed, 12 supplied. .. code-block:: c struct node_data { long key; long data; struct bpf_rb_node node; }; struct bpf_spin_lock glock; struct bpf_rb_root groot __contains(node_data, node); Introduced by commit c31315c3aa09 ("bpf, documentation: Add graph documentation for non-owning refs") -- Cheers, Stephen Rothwell
