# HEAD: 5d6dec6fba38c3e2d408df108bb92ef4ac201f18 locking/refcount: Remove the half-implemented refcount_sub() API
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.
Thanks,
Ingo
