    SubjectRe: [PATCH 1/19] MUTEX: Introduce simple mutex implementation

    please kill these two in the simple mutex implementation - they are a
    sign of mutexes used as completions.

    another simplification: also enforce that only the owner can unlock the
    mutex. This is what we are doing in the -rt patch. (This rule also
    ensures that such mutexes can be used for priority inheritance.)
