Detailed Description

Instrumentation helpers for mutexes.

This header file provides the necessary declarations to use the mutex API with the performance schema instrumentation. In some compilers (SunStudio), 'static inline' functions, when declared but not used, are not optimized away (because they are unused) by default, so that including a static inline function from a header file does create unwanted dependencies, causing unresolved symbols at link time. Other compilers, like gcc, optimize these dependencies by default.
