The patchset is desinged to test THP functionality.
when one process allocate hugepage aligned anonymouse pages,
kernel thread 'khugepaged' controlled by sysfs knobs
/sys/kernel/mm/transparent_hugepage/* will scan them, and make
them as transparent hugepage if they are suited, you can find out
how many transparent hugepages are there in one process from
/proc/<pid>/smaps, among the file contents, 'AnonHugePages' entry
stand for transparent hugepage.

accepted Wanlong's suggestion, added some comment for '10s'
added 'static' key word for single-file-only variant.
