[GIT PULL] io_uring fixes for 7.2-rc4

Hi Linus,

A small set of io_uring fixes for this week. This pull request contains:

- Fix a use-after-free in the bpf-ops struct_ops path, where the same
  io_uring_bpf_ops map could be registered more than once.

- Fix the deferred iovec free for the provided-buffer grow path, which
  could leave the caller with a dangling iovec and result in repeated
  frees. Follow-up to the earlier fix in this series.

- Zero-check the unused addr3/pad2 SQE fields for unlinkat

Please pull!
