A subsequent commit will allow uring_cmds to files that don't implement ->uring_cmd_iopoll() to be issued to IORING_SETUP_IOPOLL io_urings. This means the ctx's IORING_SETUP_IOPOLL flag isn't sufficient to determine whether a given request needs to be iopolled. Introduce a request flag REQ_F_IOPOLL set in ->issue() if a request needs to be iopolled to completion. Set the flag in io_rw_init_file() and io_uring_cmd() for requests issued to IORING_SETUP_IOPOLL ctxs. Use the request flag instead of IORING_SETUP_IOPOLL in places dealing with a specific request. A future possibility would be to add an option to enable/disable iopoll in the io_uring SQE instead of determining it from IORING_SETUP_IOPOLL.
