There is bunch of inconsistencies in the naming of NMT related files, classes and objects.

I will try to compile the issues here. Then we can see if we can agree on a common naming scheme. Then we can fix it, if we want to.

#1 Names of the NMT related locks:

Mutex* NMTQuery_lock = nullptr;
Mutex* NMTCompilationCostHistory_lock = nullptr;
Mutex* NmtVirtualMemory_lock = nullptr;

#2 Names of files:

# cd jdk/src/hotspot/share/nmt; find .
.
./memBaseline.cpp
./threadStackTracker.cpp
./memoryFileTracker.cpp
./vmatree.cpp
./nmtPreInit.hpp
./nmtCommon.cpp
./mallocTracker.hpp
./mallocLimit.cpp
./nmtDCmd.cpp
./nativeCallStackPrinter.hpp
./nmtTreap.hpp
./memTag.hpp
./nmtUsage.cpp
./arrayWithFreeList.hpp
./memLogRecorder.cpp
./memReporter.hpp
./memTracker.hpp
./allocationSite.hpp
./mallocHeader.hpp
./memMapPrinter.hpp
./nmtNativeCallStackStorage.cpp
./virtualMemoryTracker.hpp
./mallocSiteTable.cpp
./memTracker.inline.hpp
./nativeCallStackPrinter.cpp
./mallocTracker.inline.hpp
./nmtUsage.hpp
./memTagBitmap.hpp
./memTracker.cpp
./memReporter.cpp

./memoryFileTracker.hpp
./vmatree.hpp
./nmtPreInit.cpp
./nmtCommon.hpp
./mallocTracker.cpp
./mallocLimit.hpp

./nmtDCmd.hpp

Names of the files with "nmt":

# find . | grep -i nmt
./nmtPreInit.hpp
./nmtCommon.cpp
./nmtDCmd.cpp
./nmtTreap.hpp
./nmtUsage.cpp
./nmtNativeCallStackStorage.cpp

./nmtCommon.hpp
./nmtDCmd.hpp
