Subject: selftests/mm/cow: modify the incorrect checking parameters
Date: Mon, 13 Jan 2025 11:28:58 +0800
In run_with_memfd_hugetlb(), some error handle have passed incorrect
parameters. It should be "smem", but it was mistakenly written as "mem".
Let's fix it.
[gehao@xxxxxxxxxx: fix other errant sites, per Anshuman]
