I tend to use two tabs, others try to line up the parameters with the opening '('. But one tab is too visually similar to the body of the function. > rcu_read_lock(); > > memcg = folio_memcg_rcu(folio); > + > + if (!lru_gen_test_recent(shadow, type, &memcg_id, &pgdat, &token, > + &workingset)) Similarly here. &workingset looks like it's part of the body of the if, not part of the function call. > + goto unlock; > + > if (memcg_id != mem_cgroup_id(memcg)) > goto unlock; >
