Hi Linus,
A few small fixes that should go into the 6.3 release:
- Stop setting PF_NO_SETAFFINITY on io-wq workers. 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!
