Dylan Reid 03164ca9d8 io_uring: allocate iovecs based on returned count from the kernel ... The kernel is allowed to not only limit the number of requested entries, but also provide more than is requested. If a non-power-of-2 is requested, it will be rounded up to the next power of 2. Ensure that there are enough iovecs by allocating them based on the number returned from io_uring_setup instead of the number of entries requested.
