[PATCH v2 3/3] selftests/mm: Skip the hugetlb-madvise tests on unmet hugepage requirements

From: Nico Pache
Date: Wed Mar 06 2024 - 17:39:05 EST


Now that run_vmtests.sh does not guarantee that the correct hugepage
count is available, skip the hugetlb-madvise test if the requirements
are not met rather than failing.
