The first patch in this series has been seen before, it optimises for the common "lookup the default huge page size" operation. However this then breaks the gethugepagesizes test as it can no longer manipulate the values read as they are cached in the library.
The second patch implements a new test probe interface which allows partial exportation of interfaces into the main library. These are exposed in the header libhugetlbfs_testprobes.h and are name mangled for export in the main library. The third patch uses this new interface to allow tests to invalidate the huge page size cache in the library through a new test probe interface.
