Hi,
This patch series is in continuation to first part [1]
This series include 5 more tests taken from libhugetlbfs.

Background:
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. These patches include tests from libhugetlbfs.

ref:
1. https://lore.kernel.org/all/20221104162511.28658-1-tsahu@linux.ibm.com/

v1 -> v2
1. Fixed comments
v2 -> v3
1. Changed from setjmp/longjmp logic to check/return logic in
hugemmap10.c
2. Added a new patch to create support for custom flags in
tst_creat_unlinked api.
3. Added patch to add safe macros for posix_fadvise call.
4. Updated coding asthetics.
5. Added description along with the line of failure in hugemmap10.c
v3 -> v4
1. Removing redundant access call to check if file already exist.
and removing the retry path, as the case is very rare in PATCH[1/7].
