Hello,
I would like to report a source-proven teardown ordering bug in the
Linux kernel that can lead to a DMA-after-unmap race condition
involving ZCRX (io_uring zero-copy receive), page_pool, and netkit
queue leasing.

Executive Summary
[...] I am happy to provide more details or assist with testing.
This report reads like the product of an "AI" system. What "AI"
assisted you in preparing this report?

this question has been asked, in an effort to avoid deluging the
reporter with this question.]
