Subject: [PATCH 4/4] hugemmap04.c : Automatically mount hugetlbfs on /huge.
Firstly, mounting hugetlbfs on /tmp is not a good idea, because lots of
programs could use /tmp for other purpose. This could cause other tests fail.
Secondly, mounting hugetlbfs could be done automatically.
This patch creates a temp directory with name including the current PID,
automatically mounts hugetlbfs on the directory before test starts, and umounts
it when the test is over.
