Subject: [PATCH 4.14 12/95] IB/core: disable memory registration of filesystem-dax vmas
Date: Mon, 4 Dec 2017 16:59:36 +0100 [thread overview]
Message-ID: <20171204160046.689688269@linuxfoundation.org> (raw)
In-Reply-To: <20171204160046.206920966@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Williams <dan.j.williams@intel.com>
commit 5f1d43de54164dcfb9bfa542fcc92c1e1a1b6c1d upstream.
Until there is a solution to the dma-to-dax vs truncate problem it is
not safe to allow RDMA to create long standing memory registrations
against filesytem-dax vmas.
