Andrew,
Here is another occasion where we want special-case hugetlbfs enabling
to also apply to device-dax. I started to wonder what other hstate
conversions we might do beyond ->split() and ->pagesize(), but this
appears to be the last of the usages of hstate_vma() in
generic/non-hugetlbfs specific code paths.
This is 4.16 material.
