     fails

   - smc: avoid warning of possible recursive locking

  Current release - new code bugs:

   - vsock/virtio: suppress used length validation

   - neigh: fix crash in v6 module initialization error path

  Previous releases - regressions:

   - af_unix: fix change in behavior in read after shutdown

   - igb: fix netpoll exit with traffic, avoid warning

   - tls: fix splice_read() when starting mid-record

   - lan743x: fix deadlock in lan743x_phy_link_status_change()

   - marvell: prestera: fix bridge port operation

  Previous releases - always broken:

   - tcp_cubic: fix spurious Hystart ACK train detections for
     not-cwnd-limited flows

   - nexthop: fix refcount issues when replacing IPv6 groups

   - nexthop: fix null pointer dereference when IPv6 is not enabled

   - phylink: force link down and retrigger resolve on interface change

   - mptcp: fix delack timer length calculation and incorrect early
     clearing

   - ieee802154: handle iftypes as u32, prevent shift-out-of-bounds

   - nfc: virtual_ncidev: change default device permissions

   - netfilter: ctnetlink: fix error codes and flags used for kernel
     side filtering of dumps

   - netfilter: flowtable: fix IPv6 tunnel addr match

   - ncsi: align payload to 32-bit to fix dropped packets

   - iavf: fix deadlock and loss of config during VF interface reset

   - ice: avoid bpf_prog refcount underflow

  Misc:

   - marvell: mvpp2: increase MTU limit when XDP enabled"
