[LTP] [PATCH 00/29] Hugetlb: Migrating libhugetlbfs tests

[Tarun Sahu]

Hi,
Libhugetlbfs is not being maintained actively, and some distro is dropping
support for it. There are some tests that are good for testing hugetlb
functionality in kernel.

As per previous dicussion in RFC[1], Here, this patch series consists
of hugetlb tests taken from libhugetlbfs modified to work in ltp
environment. This series do not include all the tests, I
will post another series for the remaining tests soon.
