  rqspinlock: Reset tail when preserving queue on deadlock (2026-08-06 16:32:42 -0700)

----------------------------------------------------------------
BPF fixes:

- Fix BPF verifier to preserve full pointer state for commuted
  scalar += pointer arithmetic (Yiyang Chen, Eduard Zingerman)

- Fix a use-after-free of request sockets in the BPF TCP
  iterator batching (Jose Fernandez)

- Fix a use-after-free of sk_redir in the BPF sockmap send
  verdict path (Chengfeng Ye)

- Fix a netns reference imbalance in the BPF conntrack kfuncs
  (Chengfeng Ye)

- Fix bpf_get_fsverity_digest() dynptr assumptions and silent
  digest truncation (Eric Biggers)

- Fix bpf_tcp_{gen,check}_syncookie to check sk_state before
  sk_protocol to make sure it is a full socket (Luxiao Xu)

- Fix rqspinlock to reset the tail when preserving the queue
  on deadlock (Kumar Kartikeya Dwivedi)
