Please turn this into an actually readable inline function:

/*
* IORING_SETUP_SQE128 contexts allocate twice the normal SQE size for each
* slot.
*/
static inline size_t uring_sqe_size(struct io_ring_ctx *ctx)
{
if (ctx->flags & IORING_SETUP_SQE128)
return 2 * sizeof(struct io_uring_sqe);
return sizeof(struct io_uring_sqe);
}
