[PATCH v3 net-next 0/9] af_unix: Set skb drop reason in every kfree_skb() path.

[Kuniyuki Iwashima <kuniyu@amazon.com>]

There is a potential user for skb drop reason for AF_UNIX.

This series replaces some kfree_skb() in connect() and
sendmsg() paths and sets skb drop reason for the rest of
kfree_skb() in AF_UNIX.

    * Drop skb drop reason patches for connect() and sendmsg()
    * Restore patch 8
    * Add patch 9 replacing kfree_skb() with consume_skb() in connect()
      and sendmsg()

  v2: https://lore.kernel.org/netdev/20250112040810.14145-1-kuniyu@amazon.com/
    * Drop the old patch 6 to silence false-positive uninit warning
