Jens Axboe 223ef47431 io_uring: don't allow IORING_SETUP_NO_MMAP rings on highmem pages ... On at least arm32, but presumably any arch with highmem, if the application passes in memory that resides in highmem for the rings, then we should fail that ring creation. We fail it with -EINVAL, which is what kernels that don't support IORING_SETUP_NO_MMAP will do as well.
