Pull io_uring fixes from Jens Axboe: - Fix for a regression introduced in the io-wq worker creation logic. - Remove the allocation cache for the msg_ring io_kiocb allocations. I have a suspicion that there's a bug there, and since we just fixed one in that area, let's just yank the use of that cache entirely. It's not that important, and it kills some code. - Treat a closed ring like task exiting in that any requests that trigger post that condition should just get canceled. Doesn't fix any real issues, outside of having tasks being able to rely on that guarantee. - Fix for a bug in the network zero-copy notification mechanism, where a comparison for matching tctx/ctx for notifications was buggy in that it didn't correctly compare with the previous notification. * tag 'io_uring-6.17-20250919' of git://git.kernel.dk/linux: io_uring: fix incorrect io_kiocb reference in io_link_skb io_uring/msg_ring: kill alloc_cache for io_kiocb allocations io_uring: include dying ring in task_work "should cancel" state io_uring/io-wq: fix `max_workers` breakage and `nr_workers` underflow
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 reStructuredText 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.
