Linus Torvalds 6cbf5b3105 Locking changes for v6.8:
- lock guards:
 
    - Use lock guards in the ptrace code
 
    - Introduce conditional guards to extend to conditional lock
      primitives like mutex_trylock()/mutex_lock_interruptible()/etc.
 
 - lockdep:
 
    - Optimize 'struct lock_class' to be smaller
 
    - Update file patterns in MAINTAINERS

  locking/mutex: Clarify that mutex_unlock(), and most other sleeping locks, can still use the lock object after it's unlocked
  locking/mutex: Document that mutex_unlock() is non-atomic
  ptrace: Convert ptrace_attach() to use lock guards
  locking/lockdep: Slightly reorder 'struct lock_class' to save some memory
  MAINTAINERS: Add include/linux/lockdep*.h
  cleanup: Add conditional guard support

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.
