Revision 2e6e1fde32d7d41cf076c21060c329d3fdbce25c authored by Pavel Begunkov on 05 December 2019, 13:15:45 UTC, committed by Jens Axboe on 05 December 2019, 13:54:51 UTC
In case of an error io_submit_sqe() drops a request and continues without it, even if the request was a part of a link. Not only it doesn't cancel links, but also may execute wrong sequence of actions. Stop consuming sqes, and let the user handle errors.
