Linus Torvalds a1257b5e3b Rust changes for v6.5 
A fairly small one in terms of feature additions. Most of the changes in
 terms of lines come from the upgrade to the new version of the toolchain
 (which in turn is big due to the vendored 'alloc' crate).
 
  - Upgrade to Rust 1.68.2:
 
    This is the first such upgrade, and we will try to update it often
    from now on, in order to remain close to the latest release, until
    a minimum version (which is "in the future") can be established.
 
    The upgrade brings the stabilization of 4 features we used (and 2
    more that we used in our old 'rust' branch).
 
    Commit 3ed03f4da0 ("rust: upgrade to Rust 1.68.2") contains the
    details and rationale.
 
  - pin-init API:
 
    Several internal improvements and fixes to the pin-init API, e.g.
    allowing to use 'Self' in a struct definition with '#[pin_data]'.
 
  - 'error'  module:
 
    New 'name()' method for the 'Error' type (with 'errname()'
    integration), used to implement the 'Debug' trait for 'Error'.
 
    Add error codes from 'include/linux/errno.h' to the list of Rust
    'Error' constants.
 
    Allow specifying error type on the 'Result' type (with the default
    still being our usual 'Error' type).
 
  - 'str' module:
 
    'TryFrom' implementation for 'CStr', and new 'to_cstring()' method
    based on it.
 
  - 'sync' module:
 
    Implement 'AsRef' trait for 'Arc', allowing to use 'Arc' in code that
    is generic over smart pointer types.
 
    Add 'ptr_eq' method to 'Arc' for easier, less error prone comparison
    between two 'Arc' pointers.
 
    Reword the 'Send' safety comment for 'Arc', and avoid referencing it
    from the 'Sync' one.
 
  - 'task' module:
 
    Implement 'Send' marker for 'Task'.
 
  - 'types' module:
 
    Implement 'Send' and 'Sync' markers for 'ARef<T>' when 'T' is
    'AlwaysRefCounted', 'Send' and 'Sync'.
 
  - Other changes:
 
    Documentation improvements and '.gitattributes' change to start
    using the Rust diff driver.

README 

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.
