io_uring_buf_ring_cq_advance - advance index of provided buffer and CQ ring

       The  io_uring_buf_ring_cq_advance(3) commits count previously added buffers to the shared buffer ring br,
       making them visible to the kernel and hence consumable. This passes ownership of the buffer to the  ring.
       At  the  same  time,  it  advances  the  CQ ring of ring by count amount. This effectively bundles both a
       io_uring_buf_ring_advance(3) call and a io_uring_cq_advance(3) into one operation. Since updating  either
       ring index entails a store memory barrier, doing both at once is more efficient.

       The  __io_uring_buf_ring_cq_advance(3)  function performs the same operation, except it splits the counts
       into two separate values. It advances the CQ ring by cq_count entries, and the buffer ring  by  buf_count
       entries rather than increment both by the same value.
