REMInternal.h@ 26412

最後變更在這個檔案從26412是 25368,由 vboxsync 提交於 15 年前
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.
