Linus Torvalds f2c53ea949 Including fixes from Bluetooth, NFC and Netfilter.
Every week in this release is record-setting for number of posted
 patches. It doesn't seem like we're creating any regressions with
 all these fixes, 3 Fixes tags here point to 7.2 commits but none
 are true regression fixes. We're trying to keep the count down,
 nonetheless.
 
 Previous releases - regressions:
 
  - net: don't require the hwtstamp NDOs when a PHY provides timestamping
 
  - ipv6: fix dst leak for uncached routes
 
  - vrf: stop corrupting skb->csum when capturing CHECKSUM_COMPLETE
    packets
 
 Previous releases - always broken:
 
  - packet: use ubuf_info completion for TX_RING packets
 
  - arp: terminate device name before lookup
 
  - ipv6: do not let ipv6_find_hdr() return an offset past the packet end
 
  - udp: remove a disconnected socket from the 4-tuple hash table
 
  - sctp: discard the rest of the packet on a stale-cookie error
 
  - eth: mlx5: Bridge, fix remaining switchdev ownership gaps on merged
    eswitch
