Subject: [PATCH v2 0/3] kvm: Use huge pages for DAX-backed files
Date: Wed, 14 Nov 2018 16:51:52 -0500 [thread overview]
Message-ID: <20181114215155.259978-1-brho@google.com> (raw)
In-Reply-To: <20181109203921.178363-1-brho@google.com>
This patch series depends on dax pages not being PageReserved. Once
that is in place, these changes will let KVM use huge pages with
dax-backed files. Without the PageReserved change, KVM and DAX still
work with these patches, simply without huge pages - which is the
current situation.
