[BUG] io_uring: possible CQE32 overflow flush inconsistency in __io_cqring_overflow_flush()

[Cyber_black]

Hi Greg,

Thank you for your honest feedback. You are absolutely right that testing is essential.

I was able to compile the kernel without issues, but I cannot test it properly at the moment due to lack of a suitable test environment (no KVM/QEMU setup, limited hardware resources, and financial constraints).

If this means the report is considered invalid or cannot be accepted in its current form, please let me know clearly. I will revisit this when I have the appropriate infrastructure and resources to test it properly.

I don't want to waste maintainers' time with untested patches. Thank you for your understanding.

Best regards,
Eneshan Erdogan Karaca
