Eric Dumazet ec5b0f605b net/sched: cls_u32: fix possible leak in u32_init_knode() ... While investigating a related syzbot report, I found that whenever call to tcf_exts_init() from u32_init_knode() is failing, we end up with an elevated refcount on ht->refcnt To avoid that, only increase the refcount after all possible errors have been evaluated.
