The above doesn't belong in change log. Refer to a few change logs
in the repo to learn  how to write them.

You can also check the kernel documentation - this change log
is way too long. It doesn't clearly state what is being fixed.

In this case, "write_to_hugetlbfs" is missing because the right
config isn't enabled. Test stalls waiting for write_to_hugetlbfs
to run.

You are fixing this by checking if write_to_hugetlbfs exixts
from /mm/run_vmtests.sh

Summarize this in short description so people can understand
the change.

thanks,
