Function io_uring_cqe_shift_from_flags

src/include/liburing.h:425–429

* Returns the bit shift needed to index the CQ. * This shift is 1 for rings with big CQEs, and 0 for rings with normal CQEs. * CQE `index` can be computed as &cq.cqes[(index & cq.ring_mask) << cqe_shift]. */

 * CQE `index` can be computed as &cq.cqes[(index & cq.ring_mask) << cqe_shift].
