This pull request contains: - Fix for a potential leak of an iovec, if a specific cleanup path is used and the rw_cache is full at the time of the call. - Fix for a regression added in this cycle, where waitid should be using prober release/acquire semantics for updating the wait queue head. - Check for the cancelation bit being set for every work item processed by io-wq, not just at the start of the loop. Has no real practical implications other than to shut up syzbot doing crazy things that grossly overload a system, hence slowing down ring exit. - A few selftest additions, updating the mini_liburing that selftests use. Please pull!
