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. Based on suggestion[2], I am reposting the patches again. Also, I added suggested changes at [3]. ref: 1:https://lore.kernel.org/all/20220908173947.17956-1-tsahu@linux.ibm.com/ 2:https://lore.kernel.org/all/87wn8xi61v.fsf@suse.de/ 3:https://lore.kernel.org/all/20221016125731.249078-1-tsahu@linux.ibm.com/ v1 -> v2 1. In (brk near huge) test [PATCH 1/3] removed unused library function test_addr_huge() and read_maps(). v2 -> v3 1. Added a new patch commit for two new flags "needs_hugetlbfs" & "needs_unlinked_hugetlb_file" in tst_test and modified tests to use these flags. 2. Added taint check in test [PATCH 1/3]. 3. Removed redundant Hopt and nr_opt option. 4. Corrected pre-processor ARCH based conditional flags in test [PATCH 1/3] v3 -> v4 1. Removed the needs_unlinked_hugetlb_file option in PATCH[1/4]. 2. Removed the redundant saved_oc_hugepages checks in PATCH[3/4]. 3. Updated the mntpoint checks in PATCH[1/4]. v4 -> v5 1. Removed the needs_hugetlbfs check from needs_tmpdir function, because mntpoint is now mandatory option with needs_hugetlbfs. (PATCH[1/4]) v5 -> v6 1. Edited the comment for needs_hugetlbfs PATCH[1/4]. 2. Changed TCID to tid and removed __func__ from tst_brk PATCH[1/4]. 3. Removed SAFE_UMOUNT in do_cleanup PATCH[1/4]. 4. Added the ARCH definition in Makefile PATCH[2/4]. 5. Removed ALIGN and use LTP_ALIGN PATCH[2/4]. v6 -> v7 1. Removed ppc32 check from makefile, and checked for ppc32 system at runtime in PATCH[2/4] 2. Updated the test description in PATCH[2,3,4/4]. 3. Defined macros for Hugepage related strings.
