Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking updates from Ingo Molnar:
"The main changes in this cycle were:
- Add CONFIG_REFCOUNT_FULL=y to allow the disabling of the 'full'
(robustness checked) refcount_t implementation with slightly lower
runtime overhead. (Kees Cook)
The lighter weight variant is the default. The two variants use the
same API. Having this variant was a precondition by some
maintainers to merge refcount_t cleanups.
- Add lockdep support for rtmutexes (Peter Zijlstra)
- liblockdep fixes and improvements (Sasha Levin, Ben Hutchings)
- ... misc fixes and improvements"
