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" * 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (30 commits) locking/refcount: Remove the half-implemented refcount_sub() API locking/refcount: Create unchecked atomic_t implementation locking/rtmutex: Don't initialize lockdep when not required locking/selftest: Add RT-mutex support locking/selftest: Remove the bad unlock ordering test rt_mutex: Add lockdep annotations MAINTAINERS: Claim atomic*_t maintainership locking/x86: Remove the unused atomic_inc_short() methd tools/lib/lockdep: Remove private kernel headers tools/lib/lockdep: Hide liblockdep output from test results tools/lib/lockdep: Add dummy current_gfp_context() tools/include: Add IS_ERR_OR_NULL to err.h tools/lib/lockdep: Add empty __is_[module,kernel]_percpu_address tools/lib/lockdep: Include err.h tools/include: Add (mostly) empty include/linux/sched/mm.h tools/lib/lockdep: Use LDFLAGS tools/lib/lockdep: Remove double-quotes from soname tools/lib/lockdep: Fix object file paths used in an out-of-tree build tools/lib/lockdep: Fix compilation for 4.11 tools/lib/lockdep: Don't mix fd-based and stream IO ...
