io_uring: split out splice related operations This splits out splice and tee support. Signed-off-by: Jens Axboe <axboe@kernel.dk>

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

io_uring: for requests that require async, force it Some requests require being run async as they do not support non-blocking. Instead of trying to issue these requests, getting -EAGAIN and then queueing them for async issue, rather just force async upfront. Add WARN_ON_ONCE to make sure surprising code paths do not come up, however in those cases the bug would end up being a blocking io_uring_enter(2) which should not be critical.

splice: return type ssize_t from all helpers Not sure why some splice helpers return long, maybe historic reasons. Change them all to return ssize_t to conform to the splice methods and to the rest of the helpers.

io_uring/splice: use fput() directly No point in using io_file_put() here, as we need to check if it's a fixed file in the caller anyway. Signed-off-by: Jens Axboe <axboe@kernel.dk>
