One removes the added restriction on who can submit IO, making it possible for rings shared across forks to do so. The other fixes an issue for the same kind of use case, where one exiting process would cancel all IO" * tag 'io_uring-5.5-2020-01-26' of git://git.kernel.dk/linux-block: io_uring: don't cancel all work on process exit Revert "io_uring: only allow submit from owning task"
