  Previous releases - regressions:

   - sched: limit try_bulk_dequeue_skb() batches

   - ipv4: route: prevent rt_bind_exception() from rebinding stale fnhe

   - af_unix: initialise scc_index in unix_add_edge()

   - netpoll: fix incorrect refcount handling causing incorrect cleanup

   - bluetooth: don't hold spin lock over sleeping functions

   - hsr: Fix supervision frame sending on HSRv0

   - sctp: prevent possible shift out-of-bounds

   - tipc: fix use-after-free in tipc_mon_reinit_self().

   - dsa: tag_brcm: do not mark link local traffic as offloaded

   - eth: virtio-net: fix incorrect flags recording in big mode

  Previous releases - always broken:

   - sched: initialize struct tc_ife to fix kernel-infoleak

   - wifi:
      - mac80211: reject address change while connecting
      - iwlwifi: avoid toggling links due to wrong element use

   - bluetooth: cancel mesh send timer when hdev removed

   - strparser: fix signed/unsigned mismatch bug

   - handshake: fix memory leak in tls_handshake_accept()

  Misc:

   - selftests: mptcp: fix some flaky tests"
