Folded most of it, but I left your two meta data related patches as separate as I they really should be separate. However, they need a proper commit message and signed-off-by from you. It's these two: https://git.kernel.dk/cgit/linux-block/commit/?h=for-5.19/io_uring-passthrough&id=b855a4458068722235bdf69688448820c8ddae8e https://git.kernel.dk/cgit/linux-block/commit/?h=for-5.19/io_uring-passthrough&id=2be698bdd668daeb1aad2ecd516484a62e948547 Can you do those as proper patches? I did not do your async_size changes, I think you're jetlagged eyes missed that this isn't a sizeof thing on a flexible array, it's just the offset of it. Hence for non-sqe128, the the async size is io_uring_sqe - offsetof where pdu starts, and so forth. -- Jens Axboe
