Pull locking updates from Ingo Molnar: - Disable preemption in rwsem_write_trylock()'s attempt to take the rwsem, to avoid RT tasks hogging the CPU, which managed to preempt this function after the owner has been cleared but before a new owner is set. Also add debug checks to enforce this. - Add __lockfunc to more slow path functions and add __sched to semaphore functions. - Mark spinlock APIs noinline when the respective CONFIG_INLINE_SPIN_* toggles are disabled, to reduce LTO text size. - Print more debug information when lockdep gets confused in look_up_lock_class(). - Improve header file abuse checks. - Misc cleanups * tag 'locking-core-2022-10-07' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: locking/lockdep: Print more debug information - report name and key when look_up_lock_class() got confused locking: Add __sched to semaphore functions locking/rwsem: Disable preemption while trying for rwsem lock locking: Detect includes rwlock.h outside of spinlock.h locking: Add __lockfunc to slow path functions locking/spinlocks: Mark spinlocks noinline when inline spinlocks are disabled selftests: futex: Fix 'the the' typo in comment
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.
