This has been reported in the past as it confuses some applications, as some of their threads will fail with -1/EINVAL if attempted affinitized. Most recent report was on cpusets, where enabling that with io-wq workers active will fail. Just deal with the mask changing by checking when a worker times out, and then exit if we have no work pending. - Fix an issue with passthrough support where we don't properly check if the file type has pollable uring_cmd support. - Fix a reported W=1 warning on a variable being set and unused. Add a special helper for iterating these lists that doesn't save the previous list element, if that iterator never ends up using it. Please pull!
