Hello, The 1st patch returns correct flag of UBLK_F_URING_CMD_COMP_IN_TASK. The 2nd patch add help message for deciding to build ublk_drv as module or built-in. The 3rd patch improves uses of io_uring_cmd_complete_in_task() by only touching io_uring cmd when it is necessary, so we can minimize sharing of io_uring cmd between blk-mq io and ubq daemon context. The 4th patch is one cleanup.
