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 changes the hugepage constraint in the run_vmtests.sh
script, whereas patch 2 changes the constraint in the test itself.

---
Based on 6.17-rc5.

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