source: vbox/trunk/src/VBox/VMM/REMInternal.h@ 28688

Last change on this file since 28688 was 25368, checked in by vboxsync, 15 years ago

RTCritSect,PDMCritSect,iprt/lockvalidator.h: Reworked the deadlocking detection for critical sections and preparing for lock order validation. This change generalizes the RTCRITSECT::Strict data and moves it out of the RTCRITSECT, leaving a pointer behind. This saves a bit of space in release builds.
