Fix userfaultfd_hugetlb on hosts which have more than 64 cpus. --------------------------- running userfaultfd_hugetlb --------------------------- invalid MiB Usage: <MiB> <bounces> [FAIL] Via userfaultfd.c we can know, hugetlb_size needs to meet hugetlb_size >= nr_cpus * hugepage_size. hugepage_size is often 2M, so when host cpus > 64, it requires more than 128M.
