Subject: [PATCH 0/2] mm, smaps: MMUPageSize for device-dax
Date: Thu, 07 Dec 2017 19:30:49 -0800 [thread overview]
Message-ID: <151270384965.21215.2022156459463260344.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
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.
