Pull io_uring fixes from Jens Axboe:
- Use thread info versions of flag testing, as discussed last week.
- The series enabling PF_IO_WORKER to just take signals, instead of
needing to special case that they do not in a bunch of places. Ends
up being pretty trivial to do, and then we can revert all the special
casing we're currently doing.
- Kill dead pointer assignment
- Fix hashed part of async work queue trace
- Fix sign extension issue for IORING_OP_PROVIDE_BUFFERS
- Fix a link completion ordering regression in this merge window
- Cancellation fixes

============
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.
