Subject: [PATCH 0/3] 1G transparent hugepage support for device dax
Date: Mon, 23 Jan 2017 16:47:18 -0700 [thread overview]
Message-ID: <148521477073.31533.17781371321988910714.stgit@djiang5-desk3.ch.intel.com> (raw)
The following series implements support for 1G trasparent hugepage on
x86 for device dax. The bulk of the code was written by Mathew Wilcox
a while back supporting transparent 1G hugepage for fs DAX. I have
forward ported the relevant bits to 4.10-rc. The current submission has
only the necessary code to support device DAX.
