Yeah not sure what's going on, but at least they are making it through... Maybe we should base this on the for-5.19/io_uring-alloc-fixed branch? The last patch needs to be updated for that anyway. I'd think the only sane check there now is if it's a multishot direct accept request, then the request must also specify IORING_FILE_INDEX_ALLOC to ensure that we allocate descriptors. -- Jens Axboe
