Pull pin-init updates from Benno Lossin:
"Added:
- 'Wrapper<T>' trait for creating pin-initializers for wrapper
structs with a structurally pinned value such as 'UnsafeCell<T>' or
'MaybeUninit<T>'.
- 'MaybeZeroable' derive macro to try to derive 'Zeroable', but not
error if not all fields implement it. This is needed to derive
'Zeroable' for all bindgen-generated structs.
- 'unsafe fn cast_[pin_]init()' functions to unsafely change the
initialized type of an initializer. These are utilized by the
'Wrapper<T>' implementations.
Changed:
- Added support for visibility in 'Zeroable' derive macro.
- Added support for 'union's in 'Zeroable' derive macro.
Upstream dev news:
- The CI has been streamlined & some bugs with it have been fixed. I
also added new workflows to check if the user-space version and the
one in the kernel tree have diverged.
- I also started to use the issues [1] tab to keep track of any
problems or unexpected/unwanted things. This should help folks
report and diagnose issues w.r.t. 'pin-init' better.

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.
