Pull io_uring fixes from Jens Axboe: - 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. * tag 'io_uring-6.3-2023-03-09' of git://git.kernel.dk/linux: io_uring: silence variable ‘prev’ set but not used warning io_uring/uring_cmd: ensure that device supports IOPOLL io_uring/io-wq: stop setting PF_NO_SETAFFINITY on io-wq workers
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
