That's rather disappointing. :/ It looks like Jens did a fix for this (44a9bd18a0f06bba " io_uring: fix failure to verify SQ_AFF cpu") which is in the 5.2-rc series but which hasn’t been applied to the stable series yet. I am not sure how I missed that but it makes my patch redundant. Jens, will 44a9bd18a0f06bba be applied to stable kernels? Stephen
