This series enables support for forcing no-offload for requests that otherwise would have been punted to io-wq. In essence, it bypasses the normal non-blocking issue in favor of just letting the issue block. This is only done for requests that would've otherwise hit io-wq in the offload path, anything pollable will still be doing non-blocking issue. See patch 3 for details. Git tree: https://git.kernel.dk/cgit/linux/log/?h=io_uring-sync-issue Since v1: - Get rid of per-io_kiocb state, only apply this logic off the direct and initial submission path. Add IO_URING_F_NO_OFFLOAD for that. - Due to the above, drop the two first prep patches as they are no longer needed. - Make it mutually exclusive with IORING_SETUP_IOPOLL. -- Jens Axboe
