Mutexes Terminology Index

Mutexes Terms

• Robust Mutex - http://developer.osdl.org/dev/robustmutexes/
  The Robust Mutex refers to the abovementioned OSDL opensource project. The Robust mutex is also referred to using the term Fusyn . The Robust Mutex/Fusyn project implements a Posixcompliant priority-inheriting mutex, that interfaces from user space via NPTL.
• RT Mutex - http://people.redhat.com/~mingo/realtime-preempt/
  The RT Mutex is a generic priority-inheriting kernel mutex implementation used to facilitate the fully preemptable RealTime Linux kernel. The RT mutex is not Posix compliant and is not visible to user space. The RT mutex is designed to replace the system semaphore, and legacy kernel spin locks, when a fully preemptable realtime kernel is compiled.
