Li Wang
liwang@redhat.com
Mon May 23 06:59:08 CEST 2016
* take use of some SAFE Marcos
* move the intialization operations to setup()
* merge madvise0[3|4] into madvise01
* create the test file on tmpfs
* create new array madvise_opt[]
* add "MADV_HWPOISON, MADV_HUGEPAGE, MADV_NOHUGEPAGE
MADV_MERGEABLE, MADV_UNMERGEABLE" in test option
