Hi Sasha,

Unless I am missing something, the fix is already present in both trees:

  6.6.y:  b9826e3b26ec ("io_uring: prevent opcode speculation"),
          included since v6.6.80
  6.12.y: 506b9b5e8c2d ("io_uring: prevent opcode speculation"),
          included since v6.12.17

Both commits explicitly reference upstream commit 1e988c3fe126 and were
committed on February 27, 2025.

Could you please re-check and queue the 5.10 backport?
