Subject: [PATCH 0/2] selftests/mm: uffd-stress fixes

This patchset ensures that the number of hugepages is correctly set in the
system so that the uffd-stress test does not fail due to the racy nature of
the test. Patch 1 corrects the hugepage constraint in the run_vmtests.sh
script, whereas patch 2 corrects the constraint in the test itself.

Dev Jain (2):
  selftests/mm/uffd-stress: Make test operate on less hugetlb memory
  selftests/mm/uffd-stress: Stricten constraint on free hugepages before
    the test
