2022-08-23	io_uring: fix submission-failure handling for uring-cmd	Kanchan Joshi
	If ->uring_cmd returned an error value different from -EAGAIN or -EIOCBQUEUED, it gets overridden with IOU_OK. This invites trouble as caller (io_uring core code) handles IOU_OK differently than other error codes. Fix this by returning the actual error code.

2022-08-13	io_uring: make io_kiocb_to_cmd() typesafe	Stefan Metzmacher
	We need to make sure (at build time) that struct io_cmd_data is not casted to a structure that's larger.

2022-08-11	io_uring: fix error handling for io_uring_cmd	Anuj Gupta
	Commit 97b388d70b53 ("io_uring: handle completions in the core") moved the error handling from handler to core. But for io_uring_cmd handler we end up completing more than once (both in handler and in core) leading to use_after_free. Change io_uring_cmd handler to avoid calling io_uring_cmd_done in case of error.

2022-08-03	io_uring: pass correct parameters to io_req_set_res	Ming Lei
	The two parameters of 'res' and 'cflags' are swapped, so fix it. Without this fix, 'ublk del' hangs forever.

2022-07-25	io_uring: kill extra io_uring_types.h includes	Pavel Begunkov
	io_uring/io_uring.h already includes io_uring_types.h, no need to include it every time. Kill it in a bunch of places, it prepares us for following patches.
