IORING_REGISTER_PBUF_RING can reuse an old struct io_buffer_list if it was created for legacy selected buffer and has been emptied. It violates the requirement that most of the field should stay stable after publish. Always reallocate it instead.
Just a note that it should apply to 6.13 and 6.12, can you pick it for both of them?
Now done, thanks!
Great, thanks
