Subject: Re: [PATCH v1 0/2] selftests/mm: hugetlb_fault_after_madv improvements

This series has been successfully tested. Now when executing the
hugetlb_fault_after_madv selftest the benefits of both patches could
be observed.
# ./hugetlb_fault_after_madv
TAP version 13
1..1
# [INFO] detected default hugetlb page size: 1024 KiB
ok 1 SIGBUS behavior
# Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0
