Re: [PATCH] selftests/mm: hugetlb_madv_vs_map: Avoid test skipping by querying hugepage size at runtime

Am 09.05.24 um 11:54 schrieb Dev Jain:

Currently, the size used in mmap() is statically defined, leading to skipping of the test on a hugepage size other than 2 MB, since munmap() won't free the hugepage for a size greater than 2 MB. Hence, query the size at runtime.

Also, there is no reason why a hugepage allocation should fail, since we are using a simple mmap() using MAP_HUGETLB; hence, instead of skipping the test, make it fail. Signed-off-by: Dev Jain dev.jain@arm.com

Likely it would make sense to rewrite that test to try with all available hugetlb sizes (like cow.c does).
