From c33e779aba6804778c1440192a8033a145ba588d Mon Sep 17 00:00:00 2001 From: Caleb Sander Mateos Date: Fri, 31 Oct 2025 14:34:29 -0600 Subject: io_uring: add wrapper type for io_req_tw_func_t arg In preparation for uring_cmd implementations to implement functions with the io_req_tw_func_t signature, introduce a wrapper struct io_tw_req to hide the struct io_kiocb * argument. The intention is for only the io_uring core to access the inner struct io_kiocb *. uring_cmd implementations should instead call a helper from io_uring/cmd.h to convert struct io_tw_req to struct io_uring_cmd *.
