io_iopoll_req_issued

函数名称：After the iocb has been issued, it's safe to be found on the poll list.* Adding the kiocb to the list AFTER submission ensures that we don't* find it from a io_iopoll_getevents() thread before the issuer is done* accessing the kiocb cookie.

函数原型：static void io_iopoll_req_issued(struct io_kiocb *req)

返回类型：void

参数：

list_req等于list_first_entry - get the first element from a list*@ptr: the list head to take the element from.*@type: the type of the struct this is embedded in.*@member: the name of the list_head within the struct.* Note, that list is expected to be not empty.( & * ->poll_list is protected by the ctx->uring_lock for * io_uring instances that don't use IORING_SETUP_SQPOLL. * For SQPOLL, only the single threaded io_sq_thread() will * manipulate the list, hence no extra locking is needed there., structio_kiocb, list)
